Local Fault-tolerant Quantum Computation
Krysta M. Svore, Barbara M. Terhal, David P. DiVincenzo
We analyze and study the effects of locality on the fault-tolerance threshold for quantum computation. We analytically estimate how the threshold will depend on a scale parameter r…
Security Trade-offs in Ancilla-Free Quantum Bit Commitment in the Presence of Superselection Rules
D. P. DiVincenzo, J. A. Smolin, B. M. Terhal
Security trade-offs have been established for one-way bit commitment in quant-ph/0106019. We study this trade-off in two superselection settings. We show that for an `abelian' supe…
Fermionic Linear Optics Revisited
David. P. DiVincenzo, Barbara M. Terhal
We provide an alternative view of the efficient classical simulatibility of fermionic linear optics in terms of Slater determinants. We investigate the generic effects of two-mode…
Charge detection enables free-electron quantum computation
C. W. J. Beenakker, D. P. DiVincenzo, C. Emary +1
It is known that a quantum computer operating on electron-spin qubits with single-electron Hamiltonians and assisted by single-spin measurements can be simulated efficiently on a c…
Hiding Quantum Data
David P. DiVincenzo, Patrick Hayden, Barbara M. Terhal
Recent work has shown how to use the laws of quantum mechanics to keep classical and quantum bits secret in a number of different circumstances. Among the examples are private quan…
Encoded Universality from a Single Physical Interaction
J. Kempe, D. Bacon, D. P. DiVincenzo +1
We present a theoretical analysis of the paradigm of encoded universality, using a Lie algebraic analysis to derive specific conditions under which physical interactions can provid…
