Innovative Quantum Detection Technology is Reshaping Dark Matter Research

In our quest to comprehend the universe, our knowledge represents just a tiny fraction of the full reality. Dark matter and dark energy constitute roughly 95% of the universe, leaving a mere 5% as “ordinary matter” that we can directly observe. Dr. Rupak Mahapatra, an experimental particle physicist at Texas A&M University, develops cutting-edge semiconductor […]

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

Physics, Quantum Physics / Valeriano Ndeyi

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

Unicorn IQM Expands Quantum Computing Globally

Physics, Quantum Physics / Marcílio Santos

Finnish quantum computing company IQM has achieved unicorn status after a $300+ million Series B round led by cybersecurity-focused investor Ten Eleven Ventures. A spinout from academia, IQM develops both on-premise quantum computers and a complementary cloud platform. While it has clients in the APAC region and the U.S., its primary market is currently Europe.

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
