Collapse and Revival of Entanglement between Qubits Interacting via a Quantum Bus
C. E. A. Jarvis, D. A. Rodrigues, B. L. Györffy +3
We study the dynamics of the Jaynes-Cummings Model for two level systems (or qubits) interacting with a quantized single mode electromagnetic cavity (or `quantum bus'). We show tha…
Generalized parity measurements
Radu Ionicioiu, Anca E. Popescu, William J. Munro +1
Measurements play an important role in quantum computing (QC), by either providing the nonlinearity required for two-qubit gates (linear optics QC), or by implementing a quantum al…
Quantum Auctions using Adiabatic Evolution: The Corrupt Auctioneer and Circuit Implementations
Saikat Guha, Tad Hogg, David Fattal +2
We examine a proposed auction using quantum states to represent bids and distributed adiabatic search to find the winner. When the auctioneer follows the protocol, the final measur…
Creating, distributing and freezing entanglement with spin chains
Irene D'Amico, Brendon W. Lovett, Timothy P. Spiller
We show how branching spin chains can be used to both generate and distribute entanglement from their natural dynamics. Such entanglement provides a useful resource, for example fo…
Quantum Computing with Spin Qubits Interacting Through Delocalized Excitons: Overcoming Hole Mixing
Brendon W. Lovett, Ahsan Nazir, Ehoud Pazy +3
As a candidate scheme for controllably coupled qubits, we consider two quantum dots, each doped with a single electron. The spin of the electron defines our qubit basis and trion s…
Selective spin coupling through a single exciton
A. Nazir, B. W. Lovett, S. D. Barrett +2
We present a novel scheme for performing a conditional phase gate between two spin qubits in adjacent semiconductor quantum dots through delocalized single exciton states, formed t…
