Quantum-hardware spectral co-design framework for multifrequency Rydberg electrometry
Song Huang, Guibin Tian, Fernando Quijandría +4
Engineering electromagnetic hardware to satisfy discrete quantum-defined spectral constraints constitutes a general spectral co-design problem for quantum systems. Here we address…
Quantum process tomography of continuous-variable gates using coherent states
Mikael Kervinen, Shahnawaz Ahmed, Marina Kudra +5
Encoding quantum information into superpositions of multiple Fock states of a harmonic oscillator can provide protection against errors, but it comes with the cost of requiring mor…
Autonomous coherence protection of a two-level system in a fluctuating environment
Fernando Quijandría, Jason Twamley
We re-examine a scheme generalized by [R. Finkelstein et al, Phys. Rev. X 11, 011008 (2021)], whose original purpose was to remove the effects of static Doppler broadening from an…
Experimental realization of deterministic and selective photon addition in a bosonic mode assisted by an ancillary qubit
Marina Kudra, Martin Jirlow, Mikael Kervinen +5
Bosonic quantum error correcting codes are primarily designed to protect against single-photon loss. To correct for this type of error, one can encode the logical qubit in code spa…
Resolving Fock states near the Kerr-free point of a superconducting resonator
Yong Lu, Marina Kudra, Timo Hillmann +4
We have designed a tunable nonlinear resonator terminated by a SNAIL (Superconducting Nonlinear Asymmetric Inductive eLement). Such a device possesses a sweet spot in which the ext…
Quantum error correction with dissipatively stabilized squeezed cat qubits
Timo Hillmann, Fernando Quijandría
Noise-biased qubits are a promising route toward significantly reducing the hardware overhead associated with quantum error correction. The squeezed cat code, a non-local encoding…
