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,…
