Autoparametric Resonance Extending the Bit-Flip Time of a Cat Qubit up to 0.3 s
A. Marquet et al.
Phys. Rev. X 14, 021019 (2024)Cat qubits—a promising route for quantum error correction—can be stabilized with engineered dissipation. A method for increasing the dissipation rate shows greater resiliency of such a qubit to bit-flip errors.

Unified Treatment of Light Emission by Inelastic Tunneling: Interaction of Electrons and Photons beyond the Gap
Unai Muniain, Ruben Esteban, Javier Aizpurua, and Jean-Jacques Greffet
Phys. Rev. X 14, 021017 (2024)An extended theory of electrical transport illuminates how light is emitted when an electrical current flows through a metal-insulator-metal tunneling junction.

Kapitza Stabilization of Quantum Critical Order
Dushko Kuzmanovski et al.
Phys. Rev. X 14, 021016 (2024)Using the electric field of a laser pulse to rapidly shake the atoms in a material can stabilize a ferroelectric state, a proposal that extends the concept of “Kapitza engineering” to quantum critical points.
