On September 12, 2025, Quantum Zeitgeist reported on research by Kwok Ho Wan (Imperial College London), Zhenghao Zhong (University of Oxford), and colleagues. The team developed a method to simulate magic state cultivation—a process essential for fault-tolerant quantum computation—using significantly fewer computational steps.

News – Quantum experiment rewinds and fast-forwards particles in time
On September 12, 2025, GameStar reported on a breakthrough by Austrian researchers: they developed a technique that can “rewind” or “fast-forward” the state of photons or qubits, effectively allowing quantum systems to travel backward or forward in time on microscopic scales. The method, based on a so-called Quantum Switch, was successfully demonstrated with photons and superconducting qubits. A binary measurement (0 or 1) indicates whether the temporal manipulation succeeded, collapsing the superposition into a defined outcome.

Scientists at Goethe University Frankfurt have, for the first time, directly imaged atomic motion at the quantum level using the world’s most powerful X-ray laser. Their observations reveal the continuous “dance” of particles, even at absolute zero, confirming the quantum mechanical zero-point motion within larger molecules. The results were published in Nature.

According to a new report by Johann Grolle (SPIEGEL), the so-called “Q-Day” could mark a dramatic turning point in computing history. “Q” refers to quantum computers, the next generation of machines expected to be thousands of times faster than today’s classical supercomputers. Already, a quantum computer commissioned by Google six years ago solved a mathematical problem in under three and a half minutes that would have taken traditional supercomputers thousands of years.
