Harvard-Lead Phase of Multi- Qubit Systems Based on Electron Spins in Coupled Quantum Dots Project Meeting

Abstract

This is a final report for the IARPA MQCO Spin Qubits team ending in Dec. 2012, when the lead PI, Charles Marcus, moved from Harvard University to University of Copenhagen to direct the Center for Quantum Devices there. The Spin Qubits team comprises experimental and theoretical physicists, and materials scientists, working to realized gate confined multi-qubit systems in GaAs heterostructures. At the completion of the phase covered by this report, two versions of two-qubit systems were in hand, based on both singlet-triplet qubits and Loss-DiVincenzo qubits, but a successful system of three or more qubits had not been realized. The resonant exchange qubit, which allows resonant and single-gate two-qubit operation, and also been demonstrated at the one qubit level, but not for two or more qubits.
