Quantum Journal Club: Robust quantum-network memory using decoherence-protected subspaces of nuclear spins
Abstract: The realization of a network of quantum registers is an outstanding challenge in quantum science and technology. We experimentally investigate a network node that consists of a single nitro...

Quantum Journal Club: Preparation of Entangled States through Hilbert Space Engineering
Abstract: We apply laser fields to trapped atomic ions to constrain the quantum dynamics from a simultaneously applied global microwave field to an initial product state and a target entangled state....

Statistical Mechanics with Trapped Ion Coulomb Crystals
Abstract: While thermodynamics of physical systems in equilibrium is well-understood, non-equilibrium statistical mechanics still poses many open questions both in the classical and the quantum world...

Critical thermalization of a disordered dipolar spin system in diamond
Abstract: Statistical mechanics underlies our understanding of macroscopic quantum systems. It is based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium states, fo...

Enhancing quantum sensing sensitivity by a quantum memory
Abstract: In quantum sensing, precision is typically limited by the maximum time interval over which phase can be accumulated. Memories have been used to enhance this time interval beyond the coheren...

Quantum Journal Club: Extending the lifetime of a quantum bit with error correction in superconducting circuits
Abstract: Quantum error correction (QEC) can overcome the errors experienced by qubits1 and is therefore an essential component of a future quantum computer. To implement QEC, a qubit is redundantly ...
