In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead typically as

Probing XY phase transitions in a Josephson junction array with tunable frustration

Autor: Cosmic, R., Kawabata, K., Ashida, Y., Ikegami, H., Furukawa, S., Patil, P., Taylor, J. M., Nakamura, Y.

The seminal theoretical works of Berezinskii, Kosterlitz, and Thouless presented a new paradigm for phase transitions in condensed matter that are driven by topological excitations. These transitions have been extensively studied in the context of tw

Implementation of pairwise longitudinal coupling in a three-qubit superconducting circuit

Autor: Roy, Tanay, Kundu, Suman, Chand, Madhavi, Hazra, Sumeru, Nehra, N., Cosmic, R., Ranadive, A., Patankar, Meghan P., Damle, Kedar, Vijay, R.

We present the "trimon", a multi-mode superconducting circuit implementing three qubits with all-to-all longitudinal coupling. This always-on interaction enables simple implementation of generalized controlled-NOT gates which form a universal set. Fu
