Two-qubit gates for the soft 0-π qubit
Zhenxing Liu, Eli Weissler, Joshua Combes
The 0-π qubit promises longer lifetimes than the transmon, making it a strong candidate for a next-generation, lower-error qubit. Gyenis et al. experimentally demonstrated an unpro…
Revisiting the multi-mode rhombus circuit as a biased-noise qubit
Pablo Aramburu Sanchez, Trevyn F. Q. Larson, Anthony P. McFadden +3
In this work, we revisit the idea of using an interferometer of pairs of Josephson junctions as a protected rhombus qubit. Unlike in the original proposal, where the qubit states a…
Representation theory of inhomogeneous Gaussian unitaries
Jingqi Sun, Joshua Combes, Lucas Hackl
Gaussian unitaries, generated by quadratic Hamiltonians, are fundamental in quantum optics and continuous-variable computing. Their structures correspond to symplectic (bosons) and…
Enumeration of all superconducting circuits up to 5 nodes
Eli J. Weissler, Mohit Bhat, Zhenxing Liu +1
Nonlinear superconducting circuits can be used as amplifiers, transducers, and qubits. Only a handful have been analyzed or built, so useful configurations likely remain undiscover…
The performance of random bosonic rotation codes
Saurabh Totey, Akira Kyle, Steven Liu +3
Bosonic error correcting codes utilize the infinite dimensional Hilbert space of a harmonic oscillator to encode a qubit. Bosonic rotation codes are characterized by a discrete rot…
Explicit error-correction scheme and code distance for bosonic codes with rotational symmetry
Benjamin Marinoff, Miles Bush, Joshua Combes
Bosonic codes with rotational symmetry are currently one of the best performing quantum error correcting codes. Little is known about error propagation and code distance for these…
Quantum Hypercube States
L. A. Howard, T. J. Weinhold, F. Shahandeh +4
We introduce quantum hypercube states, a class of continuous-variable quantum states that are generated as orthographic projections of hypercubes onto the quadrature phase-space of…
