May 29, 2025 | Toronto, Canada — In a groundbreaking milestone for both quantum computing and fundamental physics, Dr. Zuhair Ahmed of the Centre of Excellence for Technology Quantum and AI (CETQAP), Canada, has conducted the first-ever physical measurement of quantum spacetime foam—a feat once thought impossible. Using IBM’s Sherbrooke superconducting quantum computer, the experiment revealed 92.7% localized curvature deformation in a simulated quantum patch of spacetime, potentially placing this achievement alongside the legendary breakthroughs of Grover’s and Shor’s quantum algorithms—and into serious Nobel Prize consideration.

What Was Achieved

On May 18, 2025, at exactly 08:30:07 PST, Dr. Ahmed’s quantum experiment took a purely theoretical idea—John Wheeler’s 1955 concept of quantum spacetime foam—and transformed it into measurable data using real qubits and entanglement entropy. The study directly measured localized curvature in “Patch-1” of a simulated 3-qubit spacetime model, marking the first time quantum foam has been physically probed.

Why It Matters

Until now, quantum foam has remained in the domain of theory and indirect astrophysical inference. Dr. Ahmed’s experiment changes that forever. Using Qiskit on IBM’s superconducting quantum hardware, he successfully linked quantum entanglement to spacetime curvature, demonstrating that quantum computers can directly study the geometry of the universe itself.

“This breakthrough shows that quantum computers can do more than algorithms—they can explore the fabric of reality,” said Dr. Ahmed.

A Global First

No prior effort—by any country or scientist—has performed a physical measurement of spacetime foam. The experiment leapfrogs over decades of theoretical proposals by physicists such as John Wheeler, Jacob Bekenstein, and Giovanni Amelino-Camelia, as well as observational limits set by NASA’s Fermi and Chandra space telescopes.

Key Results

• State ‘100’ (curvature in Patch-1 only) dominated the output with a quasi-probability of 0.927

• Entanglement entropy:

  • Patch 1: 0.85

  • Patch 2: 0.9

  • Patch 3: 0.0 (flat)

• All results were achieved on IBM Sherbrooke’s noisy intermediate-scale quantum (NISQ) system

A Landmark on Par with Grover and Shor

Experts suggest this achievement could rival the impact of Grover’s and Shor’s algorithms, which revolutionized quantum computing by demonstrating its power over classical computation. In comparison, Dr. Ahmed’s work revolutionizes how we study fundamental physics, using quantum computation to measure structures that exist at the Planck scale.

By simulating spacetime foam directly on real quantum hardware, the experiment may not only redefine quantum gravity research but also earn recognition from Nobel committees, as it provides the first direct window into the quantum structure of spacetime.

Implications for Science and Technology

This experiment unlocks new paths for:

• Testing quantum gravity models like string theory and loop quantum gravity

• Simulating black holes, wormholes, and the early universe

• Developing novel quantum error correction techniques

• Exploring dark energy and dark matter using measurable spacetime geometry
