Learning Correlated Noise in a 39-Qubit Quantum Processor
R. Harper, S. Flammia·Mar 1, 2023
Building error-corrected quantum computers relies crucially on measuring and modeling noise on candidate devices. In particular, optimal error correction requires knowing the noise that occurs in the device as it executes the circuits required for er...
Engineering phonon-phonon interactions in multimode circuit quantum acousto-dynamics
Uwe von Lupke, I. C. Rodrigues, Yu Yang +2 more·Mar 1, 2023
In recent years, remarkable progress has been made towards encoding and processing quantum information in the large Hilbert space of bosonic modes. Mechanical resonators are of great interest for this purpose, since they confine many high quality fac...
Real-time decoding for fault-tolerant quantum computing: progress, challenges and outlook
F. Battistel, C. Chamberland, Kauser Johar +5 more·Feb 28, 2023
Quantum computing is poised to solve practically useful problems which are computationally intractable for classical supercomputers. However, the current generation of quantum computers are limited by errors that may only partially be mitigated by de...
Variational quantum eigensolvers in the era of distributed quantum computers
Ilia Khait, Edwin Tham, D. Segal +1 more·Feb 27, 2023
The computational power of a quantum computer is limited by the number of qubits available for information processing. Increasing this number within a single device is difficult; it is widely accepted that distributed modular architectures are the so...
Repeated Purification versus Concatenated Error Correction in Fault Tolerant Quantum Networks
M. Barbeau, Joaquín García, E. Kranakis·Feb 27, 2023
Entanglement distribution is a core mechanism for the future quantum Internet. The quantum world is, however, a faulty environment. Hence, successful entanglement swapping is error-prone. The occurrence of quantum state errors can be mitigated using ...
Protecting entanglement between logical qubits via quantum error correction
W. Cai, X. Mu, Weiting Wang +11 more·Feb 25, 2023
Entanglement is one of the most important resources in quantum computing, cryptography and sensing. However, entanglement is also fragile, and its potential advantages are hindered by decoherence effects in experiments. Here we experimentally realize...
Quantum spherical codes
Shubham P. Jain, Joseph T. Iosue, A. Barg +1 more·Feb 22, 2023
As with classical computers, quantum computers require error-correction schemes to reliably perform useful large-scale calculations. The nature and frequency of errors depends on the quantum computing platform, and although there is a large literatur...
Shortcuts to adiabaticity in superconducting circuits for fast multi-partite state generation
F. C'ardenas-L'opez, J. C. Retamal, Xi Chen·Feb 15, 2023
Fast generation of multi-partite state is highly desirable in quantum information processing. By building on shortcut to adiabaticity, the authors accelerate the generation of multi-partite entangled states via reverse engineering, opening a route to...
Superconducting Cavity Qubit with Tens of Milliseconds Single-Photon Coherence Time
O. Milul, Barkay Guttel, Uri Goldblatt +7 more·Feb 13, 2023
Storing quantum information for an extended period of time is essential for running quantum algorithms with low errors. Currently, superconducting quantum memories have coherence times of a few milliseconds, and surpassing this performance has remain...
Autonomous error correction of a single logical qubit using two transmons
Ziqian Li, Tanay Roy, David Rodríguez Pérez +3 more·Feb 13, 2023
Large-scale quantum computers will inevitably need quantum error correction to protect information against decoherence. Traditional error correction typically requires many qubits, along with high-efficiency error syndrome measurement and real-time f...
