Article Synopsis
- Non-equilibrium quantum transport is essential for advancing technologies like nanoelectronics and thermal management, focusing on energy and particle transfer through quantum channels.
- Using a superconducting quantum processor, researchers demonstrated non-equilibrium steady quantum transport by creating "baths" with qubit ladders, showing that particle currents were consistent regardless of how the baths were initialized.
- This study provides experimental support for theories in statistical mechanics and prethermalisation, while also allowing precise control over variables that affect steady currents, opening new avenues for exploring quantum transport in complex quantum systems.
Article Synopsis
- Topologically ordered phases of matter go beyond traditional theories of symmetry-breaking, exhibiting unique traits like long-range entanglement and resilience to local changes.
- The research focuses on observing a prethermal topologically ordered time crystal using superconducting qubits in a square lattice that are periodically driven, revealing new dynamics not seen in thermal equilibrium.
- Findings include identifying discrete time-translation symmetry breaking and demonstrating the connection to topological order through measuring topological entanglement entropy, showcasing the potential for exploring novel phases of matter with quantum processors.
