That marble-like face all cold,
That small cherish'd form
To be flung to the worm, Deep in the charnel-mould!

And crushed with shame;
And the summer and winter was, and the length of years,
And no change came.

In vain to harrow well the levell'd plain,
If thou wilt not command the seed to grow,
And shed thy blessing on the bury'd grain.

And, no doubt, for the drowned men, many will mourn;
Because the crew's sufferings must have been great,
Which, certainly, is soul-harrowing to relate.

In science:
Harrow and Low established, in particular, the equivalence between approximate 2designs and random quantum circuits as introduced in, and conjectured that a random circuit consisting of k=poly(n, t) gates from a two-qubit universal gate set yields an approximate t-design .
Convergence rates for arbitrary statistical moments of random quantum circuits
We thank Aram Harrow for encouraging comments, and Roberto I.
Comment on the paper "Random Quantum Circuits are Approximate 2-designs"
I am greatly indebted to my supervisor Aram Harrow for his teaching, support and inspiration throughout my PhD and for this I greatly thank him. I would also like to thank the whole quantum information group at Bristol and members of the Computer Science department for their support and help.
Pseudo-randomness and Learning in Quantum Computation
It has been pointed out by Harrow that one can prove a number of interesting results in quantum information based on this philosophy .
Weak multiplicativity for random quantum channels
The following example, communicated to us by Aram Harrow, provides deterministic withoutreplacement orderings that have exponentially larger norm than the with-replacement expectation.

The authors would like to thank Dimitri Bertsekas, Aram Harrow, Pablo Parrilo for many helpful conversations and suggestions.
Beneath the valley of the noncommutative arithmetic-geometric mean inequality: conjectures, case-studies, and consequences
See, for example, Harrow, Recht and Chuang .) We are dealing here with essential instances of the deep problem of derandomization.

Quantum Algorithms
It is known, that the class of harrow shaped functions and the class of functions of discrete variables are isomorphic.
The Discrete Analogue of the Operator $d^{2m}/dx^{2m}$ and its Properties
According to deﬁnition of harrow shaped functions from (34) we get the statement of property 1.
The Discrete Analogue of the Operator $d^{2m}/dx^{2m}$ and its Properties
Recently, Bravyi, Hassidim, and Harrow showed that if Pf and Pg are both unknown (i.e., given by oracles f and g ), then this testing can be done in roughly √m quantum queries to the functions.
New Results on Quantum Property Testing
Allowing quantum queries for accessing distributions, Bravyi, Hassidim, and Harrow recently showed that the L1 -distance between two unknown distributions can actually be estimated up to small error with only O(√m) queries.
New Results on Quantum Property Testing
As Bravyi, Hassidim, and Harrow also independently observed, such a lower bound can be derived from known lower bounds for the collision problem.
New Results on Quantum Property Testing
I thank Professors Dave Bacon and Aram Harrow for feedback and many useful discussions.
