A Poem
With notes still to scribe and projects still to do,
I sit here and wonder,
how will my supposition collapse when measured?
Best intentions were strong when I started this course.
but predictably, time came short when complexity came to play
I found myself factoring large numbers,
with my quantum gates still undeveloped
and classical gates far overloaded.
But no matter...
a semester does not bookend one's education
Fun was had.
Utter confusion has a strange way of stretching the mind.
And, refreshingly, it is nice to know...
there are still teachers whose ears are deaf to whining students

Slowing Qubits Down
One day I had the physical realization
That quantum bits were not very patient
They shoot through space
Parallel or in place
Unless you apply on them phase estimation.
Confessions of a Qubit
There once was a qubit who said "Damn!
It appears my whole life's a sham,
My outward depiction
Is only the fiction
Of me or my superposition."
Marital Problems
Quantum cryptography always involves
Alice and Bob's problems to solve
Were they not so dysfunctional
Perhaps we'd not be so punctual
In finding crypto protocols so convolved.
Suspicious Physicists
Quantum information theory
Also involves much entropy
Like every other subject
We can always project
That the physicists will always be leery!

Double double toil and trouble
Qubits set and states entangled.
Begin with Turing oh so dear
Then on to qubits (never fear!)
For, half zero and half one
Their power increases by the ton.
Complex spaces, those of Hilbert,
Where unitaries to do the work.
With superpositions of the states
We solve strange problems with these gates
Deutch's, Grover's, and Simon's too,
With Shor's, even crypto's easy to undo!
Now in the partial traces throw,
When pure states we don't know.
POVM's used on density matrices,
Trace distances and fidelities,
Let Alice and Bob to chat
With text Eve can't get at
Or help some fighting spouses
Flip a coin to see who gets the houses!
Double Double toil and trouble
Qubits set and states entagled
We see it in a course numbered 5-9-8
Then the quantum is learned so great.

Nielsen and Chuang book
Easier to decipher
Kitaev book "awful"
One bit of data
It's neither zero nor one
But both, a qubit
Hilbert space quantum
Closed system transformation
Is unitary
Is P in NP?
Quantum algorithms are
Mostly BQP
CNOT, Hadamard
Phase, also Toffoli gates
Are universal
Factoring is just
Order-finding. Can use
Phase estimation
Grover quantum search
Makes use of an oracle
Sounds like black magic
How can you build a
Quantum computer? Need some
Trapped, floating ions
Decoherence--noise
Can be dealt with easily--
Error correction

Quantum Poems
1)
The Alice-Bob marriage hangs in wait,
Upon an entangled qubit's state,
The strategies are clear
and yet both sides fear
For no protocol can challenge fate!
2)
These vertical hieroglyphics,
Encode a myriad of specifics,
A big picture lays.
just under the page
another piece of the universal matrix.
3)
The happiest composite system
Contains qubits living in tandem,
while no one hears
an intruder nears
And rudely measures what was random.
4)
A group of physicist perform a hoax
about a cat half-alive half-dead in a box
The equations so well worked out
And observations to tout
Only mathematicians fall for such jokes!

There was always an uncertainty about the oracle,
I kept wondering how it did the miracle.
Sometimes I used to sit and stare,
amused by the nonseparability of the EPR pair.
Quantum information is not easy to duplicate,
no machine can clone a quantum state.
to the classical world, it never occurred,
the result is the same if the measurement is deferred.
mythical, it appears, is the teleportation,
Great is the world of quantum computation.

The Quantum Leap
Massive was the ensemble collected by a superstition,
Enlightened, a big subgroup became hidden and soon decohered.
The dimension of the remaining superposition,
Can't physically be perfectly measured.
The hairs entangled, the eyebrows taking transpose,
Confusion was purified, spanning the whole space.
The arms extended linearly, the mouths grew like big O's,
Confidence was teleported, leaving no partial trace.
One Schröedinger's cat is dead with a half probability,
That none of them survives is a tiny epsilon.
How did the reality near this rarity,
An awful experiment by Maxwell's Daemon!
But paradoxical is the physics as it is deep,
Evolving in our minds is the quantum leap!
by Yaoyun Shi
With inspirations from
The Big-O's (aka The Schroedinger Cats, or The Maxwell Demons).
