Analytic Design of Accelerated Adiabatic Gates in Realistic Qubits: General Theory and Applications to Superconducting Circuits

F. Setiawan, Peter Groszkowski, Hugo Ribeiro +1

Shortcuts to adiabaticity is a general method for speeding up adiabatic quantum protocols, and has many potential applications in quantum information processing. Unfortunately, ana…

Heisenberg-limited spin-squeezing via bosonic parametric driving

Peter Groszkowski, Hoi-Kwan Lau, C. Leroux +2

Spin-spin interactions generated by a detuned cavity are a standard mechanism for generating highly entangled spin squeezed states. We show here how introducing a weak detuned para…

Control and Coherence Time Enhancement of the 0- Qubit

Agustin Di Paolo, Arne L. Grimsmo, Peter Groszkowski +2

Kitaev's 0- qubit encodes quantum information in two protected, near-degenerate states of a superconducting quantum circuit. In a recent work, we have shown that the coherence t…

Quantum control of an oscillator using stimulated nonlinearity

Andrei Vrajitoarea, Ziwen Huang, Peter Groszkowski +2

Superconducting circuits extensively rely on the Josephson junction as a nonlinear electronic element for manipulating quantum information and mediating photon interactions. Despit…

Universal stabilization of a parametrically coupled qubit

Yao Lu, Srivatsan Chakram, Nelson Leung +7

We autonomously stabilize arbitrary states of a qubit through parametric modulation of the coupling between a fixed frequency qubit and resonator. The coupling modulation is achiev…

Random access quantum information processors

R. K. Naik, N. Leung, S. Chakram +6

Qubit connectivity is an important property of a quantum processor, with an ideal processor having random access -- the ability of arbitrary qubit pairs to interact directly. Here,…
