This morning, when the sun came up, billions of humans opened their eyes and admitted into their bodies a shaft of light from space. When the stream of photons struck the retina, neurons fired. And […]
Quantum communications have rapidly progressed toward practical, large-scale networks based on quantum key distributions that spearhead the process. Quantum key distribution systems typically include a sender “Alice,” a receiver “Bob,” who generate a shared secret […]
Insider Brief VTT Technical Research Centre of Finland and IQM Quantum Computers announce the completion of Finland’s second quantum computer. The new device is a 20-qubit quantum computer, while the first one featured 5 qubits. […]
Researcher show that n-bit integers can be factorized by independently running a quantum circuit with orders of magnitude fewer qubits many times. It then use polynomial-time classical post-processing. The correctness of the algorithm relies on […]
Tommaso Demarie, CEO and co-founder of Entropica Labs, is interviewed by Yuval Boger. Tommaso and Yuval discuss Entropica Labs’ focus on quantum computing middleware, aiming to support fault-tolerant quantum error correction, their software development tools, […]
Insider Brief Researchers created a novel electron-spin qubit platform, assembled atom-by-atom on a surface. The team successfully demonstrated the ability to control multiple qubits simultaneously, which could enable single-, two-, and three-qubit gates. The paper was […]
Quantum 7, 1130 (2023). https://doi.org/10.22331/q-2023-10-09-1130 Quantum machine learning algorithms based on parameterized quantum circuits are promising candidates for near-term quantum advantage. Although these algorithms are compatible with the current generation of quantum processors, device noise […]
In 1956, David Pines formulated a phantom. He predicted the existence of seas of electric ripples that could neutralize each other, rendering the overall ocean motionless even as individual waves ebbed and flowed. The oddity, […]
A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world. Click to rate this post! [Total: 0 […]
Quantum 7, 1129 (2023). https://doi.org/10.22331/q-2023-10-09-1129 Recently, tremendous progress has been made in the field of quantum science and technologies: different platforms for quantum simulation as well as quantum computing, ranging from superconducting qubits to neutral […]
