Spin digitizer for high-fidelity readout of a cavity-coupled silicon triple quantum dot
F. Borjans, X. Mi, J. R. Petta
An important requirement for spin-based quantum information processing is reliable and fast readout of electron spin states, allowing for feedback and error correction. However, co…
Probing the Spatial Variation of the Inter-Valley Tunnel Coupling in a Silicon Triple Quantum Dot
F. Borjans, X. Zhang, X. Mi +5
Electrons confined in silicon quantum dots exhibit orbital, spin, and valley degrees of freedom. The valley degree of freedom originates from the bulk bandstructure of silicon, whi…
Split-Gate Cavity Coupler for Silicon Circuit Quantum Electrodynamics
F. Borjans, X. Croot, S. Putz +12
Coherent charge-photon and spin-photon coupling has recently been achieved in silicon double quantum dots (DQD). Here we demonstrate a versatile split-gate cavity-coupler that allo…
Long-Range Microwave Mediated Interactions Between Electron Spins
F. Borjans, X. G. Croot, X. Mi +2
Entangling gates for electron spins in semiconductor quantum dots are generally based on exchange, a short-ranged interaction that requires wavefunction overlap. Coherent spin-phot…
Flopping-mode electric dipole spin resonance
X. Croot, X. Mi, S. Putz +4
Traditional approaches to controlling single spins in quantum dots require the generation of large electromagnetic fields to drive many Rabi oscillations within the spin coherence…
Single-Spin Relaxation in a Synthetic Spin-Orbit Field
F. Borjans, D. M. Zajac, T. M. Hazard +1
Strong magnetic field gradients can produce a synthetic spin-orbit interaction that allows for high fidelity electrical control of single electron spins. We investigate how a field…
