Journal ArticleDOI
Confining the state of light to a quantum manifold by engineered two-photon loss
Zaki Leghtas,Steven Touzard,Ioan Pop,Angela Kou,Brian Vlastakis,Andrei Petrenko,Katrina Sliwa,Anirudh Narla,Shyam Shankar,Michael Hatridge,Matthew Reagor,Luigi Frunzio,Robert Schoelkopf,Mazyar Mirrahimi,Michel Devoret +14 more
TL;DR: In this article, the state of a superconducting resonator is confined to a manifold of coherent superpositions of multiple stable steady states, and a Schrodinger cat state spontaneously squeezes out of vacuum before decaying into a classical mixture.
Journal ArticleDOI
Solid-state quantum memory using the 31 P nuclear spin
John J. L. Morton,Alexei M. Tyryshkin,Richard M. Brown,Shyam Shankar,Brendon W. Lovett,Arzhang Ardavan,Thomas Schenkel,Eugene E. Haller,Eugene E. Haller,Joel W. Ager,Stephen Aplin Lyon +10 more
TL;DR: In this article, the authors demonstrate coherent storage and readout of information between electron-spin processing elements and memory elements based on a nuclear spin, using a combination of microwave and radio-frequency pulses applied to 31P donors in an isotopically pure 28Si crystal.
Journal ArticleDOI
Black-box superconducting circuit quantization.
Simon E. Nigg,Hanhee Paik,Brian Vlastakis,Gerhard Kirchmair,Shyam Shankar,Luigi Frunzio,Michel Devoret,Robert Schoelkopf,Steven Girvin +8 more
TL;DR: The semiclassical method is used to calculate numerically the low-energy spectrum of a 3D transmon system, and quantitative agreement with measurements is found.
Journal ArticleDOI
Autonomously stabilized entanglement between two superconducting quantum bits
Shyam Shankar,Michael Hatridge,Zaki Leghtas,K. Sliwa,A. Narla,Uri Vool,Steven Girvin,Luigi Frunzio,Mazyar Mirrahimi,Michel Devoret +9 more
TL;DR: This work demonstrates the stabilization of an entangled Bell state of a quantum register of two superconducting qubits for an arbitrary time using an autonomous feedback scheme that combines continuous drives along with a specifically engineered coupling between the two-qubit register and a dissipative reservoir.
Journal ArticleDOI
Quantum back-action of an individual variable-strength measurement
Michael Hatridge,Shyam Shankar,Mazyar Mirrahimi,Mazyar Mirrahimi,Flavius Schackert,K. Geerlings,T. Brecht,K. Sliwa,B. Abdo,Luigi Frunzio,Steven Girvin,Robert Schoelkopf,Michel Devoret +12 more
TL;DR: The back-action on the qubit state of a single measurement of both signal quadratures was observed and shown to produce a stochastic operation whose action is determined by the measurement result.
