00:00:00,000 --> 00:00:06,000
Hello everyone.
I guess it's time to wrap up this course.

2
00:00:06,003 --> 00:00:14,006
I hope that you found this course
enjoyable, interesting, that you learned a

3
00:00:14,006 --> 00:00:20,003
lot from it.
I certainly learned a lot from teaching

4
00:00:20,003 --> 00:00:24,018
this course.
Well, this was the first course that I've

5
00:00:24,018 --> 00:00:29,040
taught at this scale in this online
fashion, and there was, there are a lot of

6
00:00:29,040 --> 00:00:33,059
new things about it.
The lecture format, these multiple choice

7
00:00:33,059 --> 00:00:36,092
homeworks.
It took, it all took a lot of getting used

8
00:00:36,092 --> 00:00:43,055
to, and a lot of this getting used to
happened you know as, as we were going

9
00:00:43,055 --> 00:00:50,038
along so, so, you know, perhaps you have
to deal with you know.

10
00:00:50,038 --> 00:00:55,004
Things were a little rough as we, as we
started off.

11
00:00:55,004 --> 00:01:01,023
Actually, there was, there was another
aspect that we have made the course much

12
00:01:01,023 --> 00:01:08,024
rougher than, than I would have liked.
Just as we were getting started with the

13
00:01:08,024 --> 00:01:13,064
course, there were some serious and
unexpected time commitments that, came up

14
00:01:13,064 --> 00:01:17,025
for me.
And so I actually was unable to put in

15
00:01:17,025 --> 00:01:23,060
even a fraction of the time that I
anticipated investing into the course, In

16
00:01:23,060 --> 00:01:32,007
fact, if it is wasn't for your TA, Seung
Woo Shin, the course would probably have

17
00:01:32,007 --> 00:01:37,024
had to be cancelled.
He really did your man's job you know

18
00:01:37,024 --> 00:01:44,038
taking up all the slack and, and going
well beyond the call of duty in terms of,

19
00:01:44,038 --> 00:01:51,007
in terms of you know doing everything that
was, that was thrown at him.

20
00:01:51,007 --> 00:01:59,001
So if you enjoyed the course the person
you should thank is really Seung Woo Shin.

21
00:01:59,006 --> 00:02:05,003
Now, let me just, say a little bit about
the course, the way it was, it was

22
00:02:05,003 --> 00:02:09,000
organized.
I, I think I'd said this before, at the

23
00:02:09,000 --> 00:02:14,073
beginning of this, beginning of the course
that, this is based on the course we teach

24
00:02:14,073 --> 00:02:19,085
at Berkeley.
And this is roughly the first two thirds

25
00:02:19,085 --> 00:02:24,019
of that course.
The last one third of that course focuses

26
00:02:24,019 --> 00:02:31,066
on the physical implementation of, of
qubits, of quantum gates, of measurements.

27
00:02:31,066 --> 00:02:40,001
So, I have planned to, you know once this
first installation of the course was over

28
00:02:40,001 --> 00:02:47,006
I was, I was planning to depending upon
how it went possibly offer a second you

29
00:02:47,006 --> 00:02:53,007
know, segment of the course which would
deal with these final four weeks.

30
00:02:54,000 --> 00:02:58,008
You know this material on the physical
implementation.

31
00:02:59,001 --> 00:03:05,002
Possibly this, this, this second unit
might contain a few other topics.

32
00:03:05,004 --> 00:03:09,009
You know like well, there's a long list of
such topics.

33
00:03:09,009 --> 00:03:16,000
But, you know, maybe, maybe there would be
about, couple of more weeks, two or three

34
00:03:16,000 --> 00:03:22,055
weeks of those topics selected from, from
some, some list like quantum cryptography

35
00:03:22,055 --> 00:03:28,019
or you know the, more generalized
description of quantum states, which are

36
00:03:28,019 --> 00:03:34,006
called density matrices.
Which are used to, you know which are used

37
00:03:34,006 --> 00:03:40,038
to describe what quantum state look like
after they well, after they decohere which

38
00:03:40,038 --> 00:03:45,032
means you know it's, it's hard to keep
quantum state isolated form the

39
00:03:45,032 --> 00:03:48,093
environment.
And the environment actually degrades the

40
00:03:48,093 --> 00:03:51,080
state, or by through accidental
measurements.

41
00:03:51,080 --> 00:03:56,091
There is also quantum error correction,
which is used to protect quantum states

42
00:03:56,091 --> 00:04:01,064
from this kind of decoherence.
And then there are topics like the quantum

43
00:04:01,064 --> 00:04:06,067
adiabatic algorithm, that I talked about
earlier in this lecture, or quantum

44
00:04:06,067 --> 00:04:11,023
complexity theory.
So these are all possible topics that,

45
00:04:11,023 --> 00:04:18,005
that might go into such a course.
But having, you know given how this course

46
00:04:18,005 --> 00:04:24,086
actually unfolded, when there's time I, I
also have the thought of going back and

47
00:04:24,086 --> 00:04:30,071
doing this course right, you know,
investing the time that I, that I had

48
00:04:30,071 --> 00:04:36,066
expected to invest into making up the
lectures, but also modifying all that

49
00:04:36,066 --> 00:04:42,009
based on everything that I've learned from
actually teaching this course.

50
00:04:42,009 --> 00:04:50,005
And so to help to do that better, I've
created a survey in which to get your, get

51
00:04:50,005 --> 00:04:54,007
your feedback about the course your
experience of this course.

52
00:04:54,009 --> 00:04:59,063
So, so, in the survey, well the survey
starts off with the first part asks you

53
00:04:59,063 --> 00:05:03,076
about yourself.
You know these are questions that you've

54
00:05:03,076 --> 00:05:07,054
answered already.
If you have taken a previous survey there

55
00:05:07,054 --> 00:05:12,070
isn't a repeat as it that this information
is that it helps put the rest of your

56
00:05:12,070 --> 00:05:16,090
responses in context.
So, in terms of the rest of the responses,

57
00:05:16,090 --> 00:05:21,049
there are two real parts to it.
One is about your, your, your feedback

58
00:05:21,049 --> 00:05:26,031
about this particular, how this course
went, so in things like the level of

59
00:05:26,031 --> 00:05:31,099
difficulty whether it was, whether you
thought it too difficult or just a breeze

60
00:05:31,099 --> 00:05:37,032
or, or whether it was challenging but in a
nice way, you know whether you learn a lot

61
00:05:37,032 --> 00:05:43,039
of material, and even if it was
challenging in a nice way, you know what,

62
00:05:43,039 --> 00:05:49,006
what could have been done to help make
things easier, or more interesting?

63
00:05:49,006 --> 00:05:56,003
So, in the survey, you will find a lot of
questions which with, with, with a, with a

64
00:05:56,003 --> 00:06:02,031
number of boxes to take in terms of your,
you know which option best describes your

65
00:06:02,031 --> 00:06:06,040
experience.
But also, you'll find space to actually

66
00:06:06,040 --> 00:06:10,043
write in an answer.
So if you, if you have this kind of

67
00:06:10,043 --> 00:06:16,009
feedback please take the time to write
this kind of feedback because it's, it's

68
00:06:16,009 --> 00:06:22,018
probably the most useful thing, you know
it's, it's probably the most useful way

69
00:06:22,018 --> 00:06:28,012
to, to convey information back to us.
Other kinds of questions in this, about

70
00:06:28,012 --> 00:06:33,012
the course, you know the just in time
approach to presenting math.

71
00:06:33,012 --> 00:06:37,039
Did you find that useful?
Did that, was that, was that too

72
00:06:37,039 --> 00:06:41,011
disorienting for you?
Even if you found it useful could, are

73
00:06:41,011 --> 00:06:46,025
there ways, you know are there small
changes we could make that would help make

74
00:06:46,025 --> 00:06:49,060
it better?
And then there's this whole other thing

75
00:06:49,060 --> 00:06:54,052
with the multiple choice assignments.
Which actually took me a lot of time to

76
00:06:54,052 --> 00:07:00,022
get used to in terms of how to actually
reformulate questions as, multiple choice

77
00:07:00,022 --> 00:07:03,031
questions.
But, what was your experience of it?

78
00:07:03,031 --> 00:07:08,045
Was it, was it a good learning experience?
And did it get better over, over the

79
00:07:08,045 --> 00:07:12,049
course of the semester?
And then there was there, there was also

80
00:07:12,049 --> 00:07:19,038
this whole issue about grading policy and
deadlines and so on, which you know maybe

81
00:07:19,038 --> 00:07:25,065
some of you didn't enjoy.
I certainly don't enjoy making those,

82
00:07:25,065 --> 00:07:33,014
those policies up, The, the, the real
question here is given that many of you

83
00:07:33,014 --> 00:07:38,006
did not have a background in quantum
mechanics.

84
00:07:38,006 --> 00:07:44,094
And given the, the rate at which, you know
there was new material being presented in

85
00:07:44,094 --> 00:07:49,001
the, in the course.
It was, it was important for you to

86
00:07:49,001 --> 00:07:54,046
understand the previous material to,
before you actual tackle the, the new

87
00:07:54,046 --> 00:07:58,004
lectures.
So, that was, that was the whole thought

88
00:07:58,004 --> 00:08:02,006
behind keeping these deadlines, and you
know, policies.

89
00:08:02,006 --> 00:08:07,042
But, how successful it was, you know this
is something that, I'd love to have

90
00:08:07,042 --> 00:08:12,055
feedback from you about.
Just so that, just to get a sense of how,

91
00:08:12,055 --> 00:08:18,085
whether it worked well or whether there
were ways that we could modify these,

92
00:08:18,085 --> 00:08:24,090
these policies in the future.
Finally, the next part of the survey is

93
00:08:24,090 --> 00:08:31,028
about the future so what sort of material
ideally you'd like to see in the course?

94
00:08:31,028 --> 00:08:36,018
You know, should we focus on basic
material, simple, concrete, easy to

95
00:08:36,018 --> 00:08:42,039
understand or you know, it's possible also
to throw in a lot of, you know there are

96
00:08:42,039 --> 00:08:47,008
possible discussion about, and point is to
research results.

97
00:08:48,000 --> 00:08:53,004
I did a little bit of that but, you know I
could do a lot more of that.

98
00:08:53,004 --> 00:08:59,004
There's also philosophical aspects to
quantum computing, you know what it says

99
00:08:59,004 --> 00:09:02,008
about the foundations of quantum
mechanics.

100
00:09:03,007 --> 00:09:07,006
There's a physical implementation that I
talked about.

101
00:09:09,002 --> 00:09:14,008
Whether you'll be more interested in
seeing much more by the computer science

102
00:09:14,008 --> 00:09:20,006
side of the picture, with more algorithm
and quantum complexy theory, and then this

103
00:09:20,034 --> 00:09:27,007
you know there's this whole issue about
assignments, exams, how these should be

104
00:09:27,007 --> 00:09:31,008
organized.
So, you know, there, there are various

105
00:09:31,008 --> 00:09:36,006
questions to try to get your get your
feedback on these.

106
00:09:36,006 --> 00:09:42,008
And certainly if you have any other
pressing thoughts, you know, please feel

107
00:09:42,008 --> 00:09:49,001
free to, there's, there's space in the
survey for you to write, write, write

108
00:09:49,001 --> 00:09:55,008
those in and give us that feedback.
Okay, so It's time to say goodbye.

109
00:09:55,008 --> 00:10:04,007
I you know, I have to say that this was
this was really quite a rewarding

110
00:10:04,007 --> 00:10:11,003
experience.
It was quite a it was, it was it was,

111
00:10:11,003 --> 00:10:16,036
it's, it's certainly something that I
intent to, at the next.

112
00:10:16,036 --> 00:10:22,081
Next opportunity, we'll have the time to
put something together.

113
00:10:22,081 --> 00:10:30,004
I do intent to put more courses together
and I hope you enjoyed this, this course.

114
00:10:30,004 --> 00:10:31,002
Thank you.
