Quantum 9, 1777 (2025). https://doi.org/10.22331/q-2025-06-23-1777 Given a classical query algorithm as a decision tree, when does there exist a quantum query algorithm with a speed-up over the classical one? We provide a general construction based […]
A team of international researchers led by the University of Ottawa has made a breakthrough in the development of ultra-thin magnets—a discovery that could lead to faster, more energy-efficient electronics, quantum computers, and advanced communication […]
Beneath the richness of our world lies a pristine simplicity. Everything is made of a set of just 17 fundamental particles, and those particles, though they may differ by mass or charge, come in just […]
I posted this on my Facebook, but several friends asked me to share more widely, so here goes: I voted against Trump three times, and donated thousands to his opponents. I’d still vote against him […]
Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works only with infinitely long magnets, they engineered […]
In a strategic move aimed at pushing the frontier of mineral exploration, Australian space and exploration tech firm Fleet Space Technologies has announced collaborations with three quantum sensing innovators: mDetect, Nomad Atomics, and DeteQt. These […]
Embezzlement of entanglement is an exotic phenomenon in quantum information science, describing the possibility of extracting entanglement from a resource system without changing its quantum state. In this context, the resource systems play the role […]
Insider Brief Researchers at the University of Osaka have developed a more efficient method to prepare high-fidelity “magic states,” a critical step toward building fault-tolerant quantum computers. The new approach, called “level-zero” magic state distillation, […]
Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. Click to rate this post! [Total: […]
Insider Brief A new study uses quantum field theory to show that the electromagnetic field of a single photon spreads across both paths of a beam splitter, even though the photon is detected in only […]
