Logical Error Rate Scaling of the Toric Code
Fern H. E. Watson, Sean D. Barrett
To date, a great deal of attention has focused on characterizing the performance of quantum error correcting codes via their thresholds, the maximum correctable physical error rate…
Splitting a single Cooper-pair with microwave light
N. J. Lambert, M. Edwards, A. A. Esmail +4
We measure an aluminum superconducting double quantum dot and find that its electrical impedance, specifically its quantum capacitance, depends on whether or not it contains a sing…
Topological Entanglement Entropy with a Twist
Benjamin J. Brown, Stephen D. Bartlett, Andrew C. Doherty +1
Defects in topologically ordered models have interesting properties that are reminiscent of the anyonic excitations of the models themselves. For example, dislocations in the toric…
Tradeoff between Leakage and Dephasing Errors in the Fluxonium Qubit
David A. Herrera-Martí, Ahsan Nazir, Sean D. Barrett
We present a tradeoff between leakage and pure dephasing errors for the fluxonium circuit. We show that in the insulating regime, i.e., when the persistent current flowing across t…
Long range failure-tolerant entanglement distribution
Ying Li, Sean D. Barrett, Thomas M. Stace +1
We introduce a protocol to distribute entanglement between remote parties. Our protocol is based on a chain of repeater stations, and exploits topological encoding to tolerate very…
Simulating Quantum Fields with Cavity QED
Sean Barrett, Klemens Hammerer, Sarah Harrison +2
As the realization of a fully operational quantum computer remains distant, quantum simulation, whereby one quantum system is engineered to simulate another, becomes a key goal of…
