Squeezed states of the electromagnetic field find many important applications in quantum information science and quantum metrology. Dr. Jie Li et al. at Zhejiang University put forward a new mechanism for preparing microwave squeezed vacuum […]

Yonatan Cohen is the CTO of Quantum Machines. I, Brian Wang of Nextbigfuture, interviewed Yonatan at the Q2B quantum computer conference yesterday, December 6, 2022. Quantum Machines makes a comprehensive hardware and software platform for […]
Quantum 6, 873 (2022). https://doi.org/10.22331/q-2022-12-07-873 Topological data analysis (TDA) is an emergent field of data analysis. The critical step of TDA is computing the persistent Betti numbers. Existing classical algorithms for TDA are limited if […]
Researchers have used a quantum processor to make microwave photons uncharacteristically sticky. They coaxed them to clump together into bound states, then found that these photon clusters survived in a regime where they were expected […]
Quantum 6, 872 (2022). https://doi.org/10.22331/q-2022-12-07-872 The quantum Fourier transform (QFT) is a key primitive for quantum computing that is typically used as a subroutine within a larger computation, for instance for phase estimation. As such, […]
A research team co-led by a scientist at City University of Hong Kong (CityU) has developed a novel antenna that allows manipulation of the direction, frequency and amplitude of the radiated beam, and is expected […]
Quantum computers get a lot of hype, but the truth is we’re still not sure what they’ll be good for. These devices leverage the peculiar physics of the subatomic world and have the potential to […]
The JARA Institute for Quantum Information (PGI-11) of the Juelich Research Centre in Germany offers at least one PhD position. The positions are funded by German and international collaborative projects. The research will focus on […]
Quantum 6, 871 (2022). https://doi.org/10.22331/q-2022-12-07-871 We develop a framework of “semi-automatic differentiation” that combines existing gradient-based methods of quantum optimal control with automatic differentiation. The approach allows to optimize practically any computable functional and is […]
