Superconducting Circuits and Quantum Computation
... The basic component of a quantum computer is the qubit, the quantum analog to today’s bits. Any two-level quantum system could serve as a qubit; however, the qubit must satisfy two major criteria for practical quantum computing: long coherence times and the ability to scale to thousands of qubits. P ...

Schumacher Compression
... Given access to many uses of a noiseless classical channel, what is the best that a sender and receiver can make of this resource for compressed data transmission? Shannon’s compression theorem demonstrates that the Shannon entropy is the fundamental limit for the compression rate in the IID setting ...

Quantum Nash Equilibria and Quantum Computing
... creates the possibility of significantly better payoffs than classical equilibria. A quantum coordinated version of rock-paper-scissors, for example, where two players coordinate against a third produces a payoff asymptotic to 1/3 rather than 1/9. Moreover, this effect is not achievable through any ...

A Functional Architecture for Scalable Quantum Computing
... the phase shift acquired by |20i does not affect the gate fidelity. This tuning of fluxonium also affects the states |10i and |01i, creating some phase shift. This effect is usually very small because it occurs at a frequency far away from the frequency T . Note that the at which |11i and |20i repul ...
