Addressing spin transitions on 209Bi donors in silicon using circularly-polarized microwaves

T. Yasukawa, A. J. Sigillito, B. C. Rose +2

Over the past decade donor spin qubits in isotopically enriched Si have been intensely studied due to their exceptionally long coherence times. More recently bismuth donor e…

ESR measurements of phosphorus dimers in isotopically enriched 28Si silicon

S. Shankar, A. M. Tyryshkin, S. A. Lyon

Dopants in silicon have been studied for many decades using optical and electron spin resonance (ESR) spectroscopy. Recently, new features have been observed in the spectra of dopa…

Anisotropic Stark Effect and Electric-Field Noise Suppression for Phosphorus Donor Qubits in Silicon

A. J. Sigillito, A. M. Tyryshkin, S. A. Lyon

We report the use of novel, capacitively terminated coplanar waveguide (CPW) resonators to measure the quadratic Stark shift of phosphorus donor qubits in Si. We confirm that valle…

Host isotope mass effects on the hyperfine interaction of group-V donors in silicon

T. Sekiguchi, A. M. Tyryshkin, S. Tojo +12

The effects of host isotope mass on the hyperfine interaction of group-V donors in silicon are revealed by pulsed electron nuclear double resonance (ENDOR) spectroscopy of isotopic…

Stark shift and field ionization of arsenic donors in Si-SOI structures

C. C. Lo, S. Simmons, R. Lo Nardo +8

We develop an efficient back gate for silicon-on-insulator (SOI) devices operating at cryogenic temperatures, and measure the quadratic hyperfine Stark shift parameter of arsenic d…

Exchange coupling between silicon donors: the crucial role of the central cell and mass anisotropy

G. Pica, B. W. Lovett, R. N Bhatt +1

Donors in silicon are now demonstrated as one of the leading candidates for implementing qubits and quantum information processing. Single qubit operations, measurements and long c…
