John Clarke, Michel H. Devoret, and John M. Martinis receive the 2025 Nobel Prize in Physics for experiments demonstrating quantum tunneling in macroscopic circuits. Their mid-1980s work laid the foundation for superconducting quantum computers. The laureates expressed great surprise at the award.
10 martini proof links quantum mechanics to intricate math structures
A challenging mathematical proof, famously dubbed the '10 martini' problem, has been solved by connecting quantum mechanics to infinitely intricate structures. The solution employs number theory to explain quantum fractals. This breakthrough was first reported in Quanta Magazine and featured in WIRED.
Quantum computers test reality of wave function
AI에 의해 보고됨
Researchers have used a quantum computer to perform a key test suggesting that quantum mechanics accurately describes reality at small scales. The experiment confirms the 'ontic' view, where the wave function represents true quantum states. However, noise limits insights at larger scales.
Ultracold atomic clocks probe quantum effects on time
AI에 의해 보고됨
Scientists have developed highly precise ultracold atomic clocks that could detect how quantum physics influences the flow of time. By cooling atoms to near absolute zero, these devices aim to measure subtle time variations predicted by quantum theory. The research, published in Nature Communications, opens new avenues for testing fundamental physics.
New model revives Einstein's idea for universe's origin
Scientists from Spain and Italy have proposed a model that replaces cosmic inflation with gravitational waves as the key force in the universe's early formation. Published in Physical Review Research, the study suggests gravity and quantum mechanics alone can explain the cosmos's structure. This approach draws on a century-old concept linked to Albert Einstein's work.
