Protection of quantum information in a chain of Josephson junctions
Paul Brookes, Tikai Chang, Marzena Szymanska +3
Symmetry considerations are key towards our understanding of the fundamental laws of Nature. The presence of a symmetry implies that a physical system is invariant under specific t…
The Role of Spin-Flip Collisions in a Dark Exciton Condensate
Subhradeep Misra, Michael Stern, Vladimir Umansky +1
We show that a Bose-Einstein condensate consisting of dark excitons forms in GaAs coupled quantum wells at low temperatures. We find that the condensate extends over hundreds of mi…
Coherence properties of a spin in a squeezed resonator
Inbar Shani, Emanuele G. Dalla Torre, Michael Stern
A promising venue for hybrid quantum computation involves the strong coupling between impurity spins and superconducting resonators. One strategy to control and enhance this coupli…
Experimental Study of the Exciton Gas Liquid Transition in Coupled Quantum Wells
Subhradeep Misra, Michael Stern, Arjun Joshua +2
We study the exciton gas-liquid transition in GaAs/AlGaAs coupled quantum wells. Below a critical temperature, Tc=4.8K, and above a threshold laser power density the system undergo…
Coherent manipulation of Andreev states in superconducting atomic contacts
C. Janvier, L. Tosi, L. Bretheau +9
Coherent control of quantum states has been demonstrated in a variety of superconducting devices. In all these devices, the variables that are manipulated are collective electromag…
Controlling spin relaxation with a cavity
A. Bienfait, J. J. Pla, Y. Kubo +9
Spontaneous emission of radiation is one of the fundamental mechanisms by which an excited quantum system returns to equilibrium. For spins, however, spontaneous emission is genera…
Coupling a single Nitrogen-Vacancy center to a superconducting flux qubit in the far off resonance regime
Tom Douce, Michael Stern, Nicim Zagury +2
We present a theoretical proposal to couple a single Nitrogen-Vacancy (NV) center to a superconducting flux qubit (FQ) in the regime where both systems are off resonance. The coupl…
Reaching the quantum limit of sensitivity in electron spin resonance
A. Bienfait, J. J. Pla, Y. Kubo +12
We report pulsed electron-spin resonance (ESR) measurements on an ensemble of Bismuth donors in Silicon cooled at 10mK in a dilution refrigerator. Using a Josephson parametric micr…
Flux Qubits with Long Coherence Times for Hybrid Quantum Circuits
Michael Stern, Gianluigi Catelani, Yuimaru Kubo +5
We present measurements of superconducting flux qubits embedded in a three dimensional copper cavity. The qubits are fabricated on a sapphire substrate and are measured by coupling…
Exciton Liquid in Coupled Quantum Wells
Michael Stern, Vladimir Umansky, Israel Bar-Joseph
Excitons in semiconductors may form correlated phases at low temperatures. We report the observation of an exciton liquid in GaAs/AlGaAs coupled quantum wells. Above a critical den…
