Silicon quantum processor unit cell operation above one Kelvin
C. H. Yang, R. C. C. Leon, J. C. C. Hwang +12
Quantum computers are expected to outperform conventional computers for a range of important problems, from molecular simulation to search algorithms, once they can be scaled up to…
Coherent spin control of s-, p-, d- and f-electrons in a silicon quantum dot
R. C. C. Leon, C. H. Yang, J. C. C. Hwang +12
Once the periodic properties of elements were unveiled, chemical bonds could be understood in terms of the valence of atoms. Ideally, this rationale would extend to quantum dots, o…
Silicon qubit fidelities approaching incoherent noise limits via pulse engineering
C. H. Yang, K. W. Chan, R. Harper +12
The performance requirements for fault-tolerant quantum computing are very stringent. Qubits must be manipulated, coupled, and measured with error rates well below 1%. For semicond…
Fidelity benchmarks for two-qubit gates in silicon
W. Huang, C. H. Yang, K. W. Chan +10
Universal quantum computation will require qubit technology based on a scalable platform, together with quantum error correction protocols that place strict limits on the maximum i…
Impact of valley phase and splitting on readout of silicon spin qubits
M. L. V. Tagliaferri, P. L. Bavdaz, W. Huang +3
We investigate the effect of the valley degree of freedom on Pauli-spin blockade readout of spin qubits in silicon. The valley splitting energy sets the singlet-triplet splitting a…
Assessment of a silicon quantum dot spin qubit environment via noise spectroscopy
K. W. Chan, W. Huang, C. H. Yang +8
Preserving coherence long enough to perform meaningful calculations is one of the major challenges on the pathway to large scale quantum computer implementations. Noise coupled fro…
