Description
Low Temperature Detector for quantum technologies and other frontiers
Quantum information technology has turned to be a bullet train supported by many countries (EU, USA, UK, JP and CN). The quantum information process (QIP) involves quantum sources, quantum manipulation tools as well as quantum detectors. Since the photon (of visible and near infrared wavelengths) is one of the most popular quanta to play, single photon detectors (SPDs) play an irreplaceable...
Granular aluminum is an intriguing superconducting material, which has recently been receiving increasing attention in the superconducting quantum bits (qubits) and detectors communities. Among its key features are a tunable kinetic inductance up to nH/sq, amenable nonlinearity, and low microwave frequency losses [1,2,3]. Furthermore, quasiparticle relaxation times on the order of ~s have been...
Superconducting single-photon detectors have become the preferred technology for applications that require high detection efficiency, ultrafast timing performance and low noise for wide spectral sensitivity spanning UV to IR spectrum. The wide range of applications such as fundamental tests of quantum mechanics, fluorescence microscopy, optical communication and quantum computing, also...
Silicon carbide (SiC) is among the most promising optical material for the realization of classical and quantum photonics, due to the simultaneous presence of quantum emitters and a non-centrosymmetric crystal structure. In recent years, progress have been made in the development of SiC integrated optical components making this a mature platform for the implementation of quantum experiments on...
It is widely accepted that we are in the midst of a second quantum revolution. The first quantum revolution explained the nature of physical reality, and provided much of the technology that makes the modern world possible. The second quantum revolution is deploying modern tools to manipulate and control coherent quantum systems for computation, simulation, communication, and sensing /...
Photodetection plays a key role in basic science and technology, with exquisite performance having been achieved down to the single photon level. Further improvements in photodetectors would open new possibilities across a broad range of scientific disciplines, and enable new types of applications. However, it is still unclear what is possible in terms of ultimate performance, and what...
Artificial atoms based on superconducting qubits can be used to perform quantum non-demolition measurements of signal photons in microwave cavity detectors of low mass dark matter waves. By measuring only the photon wave's amplitude while remaining insensitive to the conjugate phase observable, these sensors evade the Heisenberg uncertainty principle and exhibit noise levels far below those...
The direct detection of WIMP dark matter has so far eluded detection efforts. Like WIMPs, the QCD axion is a natural dark-matter candidate, but large parts of its parameter space, including some of the most well-motivated models, remain unexplored. We describe the Dark Matter Radio (DM Radio), a low-temperature search for axions and hidden-photons over the peV$-$$\mu$eV mass range. Axion and...
