Pair-cat codes: autonomous error-correction with low-order nonlinearity

Victor V. Albert, S. Mundhada, A. Grimm +3 more·Jan 18, 2018

We introduce a driven-dissipative two-mode bosonic system whose reservoir causes simultaneous loss of two photons in each mode and whose steady states are superpositions of pair-coherent/Barut-Girardello coherent states. We show how quantum informati...

Majorana-Based Fermionic Quantum Computation.

T. O’Brien, P. Rożek, A. Akhmerov·Dec 6, 2017

Because Majorana zero modes store quantum information nonlocally, they are protected from noise, and have been proposed as a building block for a quantum computer. We show how to use the same protection from noise to implement universal fermionic qua...
