Quantum-Classical Separation in Bounded-Resource Tasks Arising from Measurement Contextuality
Shashwat Kumar, Eliott Rosenberg, Alejandro Grajales Dau +280
The prevailing view is that quantum phenomena can be harnessed to tackle certain problems beyond the reach of classical approaches. Quantifying this capability as a quantum-classic…
Generating higher order quantum dissipation from lower order parametric processes
S. O. Mundhada, A. Grimm, S. Touzard +4
Stabilization of quantum manifolds is at the heart of error-protected quantum information storage and manipulation. Nonlinear driven-dissipative processes achieve such stabilizatio…
Tracking Photon Jumps with Repeated Quantum Non-Demolition Parity Measurements
L. Sun, A. Petrenko, Z. Leghtas +11
Quantum error correction (QEC) is required for a practical quantum computer because of the fragile nature of quantum information. In QEC, information is redundantly stored in a lar…
Stabilizing a Bell state of two superconducting qubits by dissipation engineering
Z. Leghtas, U. Vool, S. Shankar +4
We propose a dissipation engineering scheme that prepares and protects a maximally entangled state of a pair of superconducting qubits. This is done by off-resonantly coupling the…
Protocol for universal gates in optimally biased superconducting qubits
Chad Rigetti, Michel Devoret
We present a new experimental protocol for performing universal gates in a register of superconducting qubits coupled by fixed on-chip linear reactances. The qubits have fixed, det…
