Scientists from Alibaba, the Chinese e-commerce giant, report they have designed a scheme that demonstrates the ability to share high-quality random numbers across a distributed network using quantum technology. In a study published in Nature, […]
The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings, led by […]
Quantum 5, 503 (2021). https://doi.org/10.22331/q-2021-07-13-503 We argue that the quantum-theoretical structures studied in several recent lines of research cannot be adequately described within the standard framework of quantum circuits. This is in particular the case […]
Quantum 5, 502 (2021). https://doi.org/10.22331/q-2021-07-13-502 Identifying computational tasks suitable for (future) quantum computers is an active field of research. Here we explore utilizing quantum computers for the purpose of solving differential equations. We consider two […]
Quantum 5, 501 (2021). https://doi.org/10.22331/q-2021-07-13-501 Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are classified by means of fundamental symmetry classes. It is instead only […]
Quantum 5, 500 (2021). https://doi.org/10.22331/q-2021-07-13-500 Energy storage is a basic physical process with many applications. When considering this task at the quantum scale, it becomes important to optimise the non-equilibrium dynamics of energy transfer to […]
Quantum 5, 499 (2021). https://doi.org/10.22331/q-2021-07-13-499 Activation of Bell nonlocality refers to the phenomenon that some entangled mixed states that admit a local hidden variable model in the standard Bell scenario nevertheless reveal their nonlocal nature […]
In recent years, physicists and electronics engineers have been trying to devise strategies to control or produce quantum states of matter in different materials. Such strategies could ultimately prove valuable for the development of new […]
Q-Sensorix’s Prototype quantum gyro $300M The quantum sensor market is a sector that is set to grow exponentially in the coming decade as the underlying technology behind it — namely quantum mechanics — is understood more. Already we can see […]
A new result from the ATLAS Collaboration at CERN studies the interactions of photons—particles of light—with lead nuclei at the Large Hadron Collider (LHC). Using new data collection techniques, physicists revealed an unexpected similarity to […]
