A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment. Click to rate this post! [Total: 0 Average: […]
A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single exotic particle behaves in a many-body system, namely as a mobile or static impurity […]
Rigetti Computing Receives $8.4 Million Order for 108-Qubit Quantum Computer from India’s C-DAC0 (0)
Rigetti Computing India P L, a wholly owned subsidiary of Rigetti Computing, Inc. (Nasdaq: RGTI), has received an $8.4 million purchase order to deliver a 108-qubit quantum computer to the Centre for Development of Advanced […]
Imagine if our skies were always filled with a thick layer of opaque clouds. With no way to see the stars, or to view our planet from above, would we have ever discovered that the […]
The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST researchers have succeeded in directly observing the moments […]
The Universidad Politécnica de Madrid (UPM), in collaboration with Q*Bird, has officially deployed Spain’s first operational Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) network. This multi-node infrastructure connects three distinct high-security sites: two locations within the Instituto […]
Quantum technologies are cutting-edge systems that can process, transfer, or store information leveraging quantum mechanical effects, particularly a phenomenon known as quantum entanglement. Entanglement entails a correlation between two or more distant particles, whereby measuring […]
Horizon Quantum Computing and Alice & Bob have announced a strategic collaboration to integrate their respective software and hardware capabilities, aimed at accelerating the deployment of fault-tolerant quantum computing (FTQC). The partnership centers on the […]
Quantum 10, 1976 (2026). https://doi.org/10.22331/q-2026-01-20-1976 Recent theoretical results in quantum machine learning have demonstrated a general trade-off between the expressive power of quantum neural networks (QNNs) and their trainability; as a corollary of these results, […]
Quantum 10, 1975 (2026). https://doi.org/10.22331/q-2026-01-20-1975 For many problems, quantum algorithms promise speedups over their classical counterparts. However, these results predominantly rely on asymptotic worst-case analysis, which overlooks significant overheads due to error correction and the […]
