Operating two exchange-only qubits in parallel
Mateusz T. Mądzik, Florian Luthi, Gian Giacomo Guerreschi +38
Semiconductors are among the most promising platforms to implement large-scale quantum computers, as advanced manufacturing techniques allow fabrication of large quantum dot arrays…
Short two-qubit pulse sequences for exchange-only spin qubits in 2D layouts
Jason D. Chadwick, Gian Giacomo Guerreschi, Florian Luthi +9
Exchange-only (EO) spin qubits in quantum dots offer an expansive design landscape for architecting scalable device layouts. The study of two-EO-qubit operations, which involve six…
Fast quantum gates for exchange-only qubits using simultaneous exchange pulses
Irina Heinz, Felix Borjans, Matthew J. Curry +6
The benefit of exchange-only qubits compared to other spin qubit types is the universal control using only voltage controlled exchange interactions between neighboring spins. As a…
Electron spin relaxation of single phosphorus donors in metal-oxide-semiconductor nanoscale devices
Stefanie B. Tenberg, Serwan Asaad, Mateusz T. Mądzik +12
We analyze the electron spin relaxation rate of individual ion-implanted P donors, in a large set of metal-oxide-semiconductor (MOS) silicon nanoscale devices, with…
