D. Dark matter particle identification
In 2025, the Physics Nobel Prize was awarded to John Clarke, Michel H. Devoret, and John M. Martinis for showing macroscopic quantum mechanical tunneling and energy quantisation in an electrical circuit.
This is a big deal. Quantum effects (like superposition or tunneling) are usually seen at atomic or subatomic scales. What the laureates did was observe such behavior in a device large enough to be handled—bringing quantum physics closer to “everyday scale.”
Their work opens doors to better quantum computers, quantum sensors, and quantum cryptography tools. Because when circuits can behave quantumly at larger scales, more stable and practical quantum machines are possible.
It’s not just theoretical. The techniques could help reduce noise in quantum devices, scale up qubit arrays, and advance the quantum technology revolution.
