Perfect initialization of a quantum computer of neutral atoms in an optical lattice of large lattice constant
J. Vala, A. V. Thapliyal, S. Myrgren +3
We propose a scheme for the initialization of a quantum computer based on neutral atoms trapped in an optical lattice with large lattice constant. Our focus is the development of a…
How Powerful is Adiabatic Quantum Computation?
Wim van Dam, Michele Mosca, Umesh Vazirani
We analyze the computational power and limitations of the recently proposed 'quantum adiabatic evolution algorithm'.
Quantum Bit Escrow
Dorit Aharonov, Amnon Ta-Shma, Umesh Vazirani +1
Unconditionally secure bit commitment and coin flipping are known to be impossible in the classical world. Bit commitment is known to be impossible also in the quantum world. We in…
Computing with highly mixed states
Andris Ambainis, Leonard J. Schulman, Umesh Vazirani
We consider quantum computing in the k-qubit model where the starting state of a quantum computer consists of k qubits in a pure state and n-k qubits in a maximally mixed state. We…
Scalable NMR Quantum Computation
Leonard J. Schulman, Umesh Vazirani
Nuclear magnetic resonance offers an appealing prospect for implementation of quantum computers, because of the long coherence times associated with nuclear spins, and extensive la…
