While entangled photons hold incredible promise for quantum computing and communications, they have a major inherent disadvantage. After one use, they simply disappear. Click to rate this post! [Total: 0 Average: 0]You have already voted […]
Update: In the comments, Craig Gidney points out that Ronit’s O(n log2 n) quantum circuits for the exact QFT were already published by Cleve and Watrous in 2000 (in a paper whose main point was […]
Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal. By monitoring how […]
Insider Brief QDNL Participations has announced the €25 million first close of its new fund, aiming to invest in early-stage quantum technology startups globally, with a target of €60 million. The firm has expanded its […]
Quantum 9, 1607 (2025). https://doi.org/10.22331/q-2025-01-23-1607 We investigate mixed states exhibiting nontrivial topological features, focusing on symmetry-protected topological (SPT) phases under various types of decoherence. Our findings demonstrate that these systems can retain topological information from […]
The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers. Qubits are the fundamental carriers of quantum information, and scientists worldwide are engineering atoms to create reliable, long-lived qubits for […]
Insider Brief D-Wave Quantum Inc. announced the completion of its $150 million “at-the-market” equity offering program, raising funds to support technical development and business operations. The program, completed at an average share price of $6.10, […]
Calculus is a powerful mathematical tool. But for hundreds of years after its invention in the 17th century, it stood on a shaky foundation. Its core concepts were rooted in intuition and informal arguments, rather […]
Quantum 9, 1606 (2025). https://doi.org/10.22331/q-2025-01-23-1606 Quantum learning tasks often leverage randomly sampled quantum circuits to characterize unknown systems. An efficient approach known as “circuit reusing,” where each circuit is executed multiple times, reduces the cost […]
In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein’s special theory of relativity. The research is published in the journal […]
