Analog Information Decoding of Bosonic Quantum Low-Density Parity-Check Codes
Popular Summary The current generation of qubit technologies are noisy, and large-scale quantum computers will need to be made fault tolerant through the use of quantum error correction.
Universal control of a bosonic mode via drive-activated native cubic interactions - Nature Communications
Abstract Linear bosonic modes offer a hardware-efficient alternative for quantum information processing but require access to some nonlinearity for universal control. The lack of nonlinearity in photonics has led to encoded measurement-based quantum computing, which relies on linear operations but requires access to resourceful (’nonlinear’) quantum states, such as cubic phase states.
Resolving Fock states near the Kerr-free point of a superconducting resonator - npj Quantum Information
Abstract We have designed a tunable nonlinear resonator terminated by a SNAIL (Superconducting Nonlinear Asymmetric Inductive eLement). Such a device possesses a Kerr-free point in which the external magnetic flux allows to suppress the Kerr interaction. We have excited photons near this Kerr-free point and characterized the device using a transmon qubit. The excitation spectrum of the qubit allows to observe photon-number-dependent frequency shifts about nine times larger than the qubit linewidth.
Quantum error correction with dissipatively stabilized squeezed-cat qubits
Abstract Noise-biased qubits are a promising route toward significantly reducing the hardware overhead associated with quantum error correction. The squeezed-cat code, a nonlocal encoding in phase space based on squeezed coherent states, is an example of a noise-biased (bosonic) qubit with exponential error bias. Here we propose and analyze the error correction performance of a dissipatively stabilized squeezed-cat qubit.
Performance of Teleportation-Based Error-Correction Circuits for Bosonic Codes with Noisy Measurements
Abstract Bosonic quantum error-correcting codes offer a viable direction towards reducing the hardware overhead required for fault-tolerant quantum information processing. A broad class of bosonic codes, namely rotation-symmetric codes, can be characterized by their phase-space rotation symmetry. However, their performance has been examined to date only within an idealistic noise model.
