Quantum computation with quantum dots
- D. Loss, D. DiVincenzo
- Physics
- 8 January 1997
We propose an implementation of a universal set of one- and two-quantum-bit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are…
The Physical Implementation of Quantum Computation

After a brief introduction to the principles and promise of quantum information processing, the requirements for the physical implementation of quantum computation are discussed. These five…
Quantum information and computation
- Charles H. Bennett, D. DiVincenzo
- Computer Science, PhysicsNature
- 1 October 1995
In information processing, as in physics, the classical world view provides an incomplete approximation to an underlying quantum reality that can be harnessed to break codes, create unbreakable codes, and speed up otherwise intractable computations.
Quantum nonlocality without entanglement
- Charles H. Bennett, D. DiVincenzo, Williams
- Physics
- 22 April 1998
We exhibit an orthogonal set of product states of two three-state particles that nevertheless cannot be reliably distinguished by a pair of separated observers ignorant of which of the states has…
Unextendible product bases and bound entanglement
- Charles H. Bennett, D. DiVincenzo, T. Mor, P. Shor, J. Smolin, B. Terhal
- Mathematics
- 18 August 1998
An unextendible product basis( UPB) for a multipartite quantum system is an incomplete orthogonal product basis whose complementary subspace contains no product state. We give examples of UPBs, and…
Classical simulation of noninteracting-fermion quantum circuits
- B. Terhal, D. DiVincenzo
- PhysicsarXiv.org
- 1 August 2001
It is shown that a class of quantum computations that was recently shown to be efficiently simulatable on a classical computer by Valiant corresponds to a physical model of noninteracting fermions in one dimension.

The entanglement of purification
- B. Terhal, M. Horodecki, D. Leung, D. DiVincenzo
- Physics
- 7 February 2002
We introduce a measure of both quantum as well as classical correlations in a quantum state, the entanglement of purification. We show that the (regularized) entanglement of purification is equal to…
The complexity of stoquastic local Hamiltonian problems
- S. Bravyi, D. DiVincenzo, R. Oliveira, B. Terhal
- PhysicsQuantum information & computation
- 16 June 2006
It is proved that LH-MIN for stoquastic Hamiltonians belongs to the complexity class AM -- a probabilistic version of NP with two rounds of communication between the prover and the verifier, and that any problem solved by adiabatic quantum computation using stoquian Hamiltonians is in PostBPP.
Quantum information processing using quantum dot spins and cavity QED
- A. Imamoğlu, D. Awschalom, A. Small
- Physics
- 28 April 1999
The electronic spin degrees of freedom in semiconductors typically have decoherence times that are several orders of magnitude longer than other relevant time scales. A solid-state quantum computer…
