New mirror made for quantum research could catch counterfeit cash

Monday, April 13, 2020 En français   Researchers at the University of Waterloo’s Institute for Quantum Computing (IQC) have developed a new kind of mirror that could be used to protect against counterfeit banknotes. Photons—quantum particles of light—can be left or right-handed, like humans. In some applications, researchers need to be able to sort left […]

Advanced microwave electronics enabling quantum technologies

Summary  Superconducting quantum computers require quantum-limited measurements at microwave frequencies in order to implement error correction. Conventionally, this is accomplished using near quantum-limited Josephson Parametric Amplifiers (JPAs). The JPAs require bulky ferrite-based circulators that prevent on-chip integration of the amplifiers with the processor and take up the majority of space and cooling power in the […]

Free-space Polarization-selective Microcavity based on Chiral Metasurfaces

Summary Developing a new type of Fabry-Pérot cavity that allows improved control of the atoms’ emission into the cavity mode will result in enhancement of the efficiency and fidelity of quantum state transfer from photons to atoms and back. This in turn can be used to improve the performance of quantum networks and repeaters, as […]

Hybrid Quantum Repeater based on Atomic Quantum Memories and Telecom Wavelength Entangled Photon-Pairs Generated from Semiconductor Nanowires

Summary   Losses in physical channels, such as optical fibres, limit existing quantum communication systems to modest distance ranges. Since amplification of quantum signals is fundamentally not possible,  we look to extend the range and functionality of these quantum channels by adding quantum memory nodes that can daisy-chain multiple lengths of quantum channels through entanglement […]

Chiral Quantum Antenna Based on Multilayer Metasurface

Summary   Individual atoms can act as stationary qubits and thus serve as nodes in quantum computing networks or as memories for quantum repeaters. However, to successfully use qubits based on single atoms suspended in free space, photons emitted by a single atom need to be efficiently collected. Conventionally, this can be done with  high […]

Spin-transfer Torque Magnetic Random Access Memory for On-chip Spin Information Storage

Summary   Leakage power in semiconductor memories, such as Dynamic Random Access Memory (DRAM) and Static Random Access Memory (SRAM), can be substantial and is one of the limits for scalability of classical electronics. This is attributed to the fact that the information stored is volatile, requiring constant refreshing, as well as reprogramming upon powering […]
