A Unique Form of Quantumness may be Key to Quantum Computers Success

Google researchers used their Willow quantum computer to show that quantum contextuality may be essential to its computational power. What gives quantum computers their edge over classical machines? A new experiment suggests that “quantum contextuality” could be a crucial factor. How Qubits Redefine Computing Quantum computers differ fundamentally from conventional machines because they exploit uniquely […]

Searching for Dark Matter Axions Using a Quantum-Enhanced Haloscope

Axions are theoretical lightweight particles that may address two major puzzles in physics: they could explain why certain nuclear interactions preserve time symmetry and may also make up dark matter. Dark matter itself does not emit, reflect, or absorb light and has yet to be directly detected. Axions are extremely light, hypothetical particles believed to

Scientists Confirm Successful Quantum Teleportation Between Photons

Physics, Quantum Physics / Marcílio Santos

Stuttgart team teleports quantum state between separate photonsThis breakthrough enables quantum information to travel long distances through repeaters made of ‘quantum dots’ without loss or interference. Unlike standard internet signals, which can be amplified along the way, quantum information requires photons that are nearly identical. Quantum dots—special semiconductors that emit light at extremely precise frequencies—can

Physicists Used a Quantum Computer to Reverse the Flow of Time

Physics, Quantum Physics / Marcílio Santos

Researchers from the Moscow Institute of Physics and Technology, working with colleagues in the U.S. and Switzerland, managed to revert a quantum computer’s state by a fraction of a second. They also estimated the probability of an electron in the vacuum of interstellar space spontaneously returning to a previous state in its own timeline. Lead

Scientists Capture First Quantum Bit Made from Antimatter

Physics, Quantum Physics / Ana Manuel

For the first time, CERN researchers have examined an antimatter particle held in a quantum superposition—a state where its properties remain undecided. Although the quantum behavior of regular matter has been thoroughly explored and applied in qubits for quantum computing, this discovery has implications far beyond technology, potentially shedding light on why the universe exists

Revealing the Planck time Limit Unlocks New Quantum Tech

Physics, Quantum Physics / Ana Manuel

A Japanese team observed “heavy fermions”—massive electrons—exhibiting quantum entanglement governed by Planckian time. This breakthrough, published in npj Quantum Materials, could lead to a new class of quantum computers using solid-state materials. Heavy fermions form when conduction electrons in a solid strongly interact with localized magnetic electrons, significantly increasing their effective mass. This interaction leads
