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.

On July 28, 2025, ScienceDaily reported a breakthrough from Kyoto University: researchers proved that quantum advantage—the point at which quantum computers outperform classical ones—is mathematically equivalent to the hardness of certain cryptographic puzzles. In other words, the same cryptographic assumptions that secure quantum-resistant systems also determine when quantum speed‑ups truly kick in.

On July 8, 2025, physicists from Aalto University in Finland achieved a major milestone: for the first time, a transmon qubit reached an echo coherence time in the millisecond range — with a peak around 1 ms and a median of approximately 0.5 ms. The previous state-of-the-art hovered below 0.6 ms.

And it’s not waiting for you to get ready.
Quantum computing isn’t some far-future abstraction anymore. It’s quietly evolving—and when it arrives at critical mass, it’ll change everything we know about cybersecurity.
Harvest Now. Decrypt Later.
Enemies are already collecting encrypted data. Not to break it today—but to crack it tomorrow, once quantum power catches up.
Call it what it is: delayed-time espionage.
