Exploring the quantum breakthroughs that could transform computing, energy, and technology
Imagine if the powerful computer on your desk or the vast data centers that power the internet could suddenly operate with perfect efficiency, losing no energy to heat. This isn't just a pipe dream—it's the promise of superconducting electronics, a field that is rapidly moving from laboratory curiosity to technological reality.

As our hunger for computational power grows, particularly with the rise of artificial intelligence and complex simulations, so does the urgent need for more efficient technology. Enter the world of superconductivity, where electricity flows with zero resistance, offering a path to revolutionary advances in everything from quantum computing to energy transmission.
Projected energy savings with superconducting technology
Heike Kamerlingh Onnes and his team discovered that cooling mercury to near absolute zero caused its electrical resistance to vanish completely 4 .
The groundbreaking Bardeen-Cooper-Schrieffer (BCS) theory finally provided the explanation: in superconductors, electrons form "Cooper pairs" that move in coordinated harmony through the material 3 9 .
John Clarke, Michel Devoret, and John Martinis conducted groundbreaking experiments with superconducting circuits, demonstrating that quantum mechanical effects could be observed on a macroscopic scale 2 .
Their work earned them the 2025 Nobel Prize in Physics, showing that a system of many superconducting particles could behave as a single quantum entity 2 .
Imagine a crowded sidewalk where everyone suddenly begins moving in perfect synchrony, effortlessly flowing toward their destination without bumping into one another—that's essentially what happens to electrons in a superconductor.
This discovery laid the foundation for one of today's most promising computing platforms: superconducting qubits, the building blocks of quantum computers.
One of the critical hurdles in making superconducting computing practical has been the efficient conversion of AC to DC power at cryogenic temperatures 1 .
The problem is particularly acute for energy-efficient rapid single flux quantum (ERSFQ) circuits, where the AC-to-DC conversion issue limits scalability and prevents implementation in larger, more complex systems 1 .
Addressing this challenge, a research team at MIT's Plasma Science and Fusion Center led by Jagadeesh Moodera engineered a breakthrough solution.
Their approach involved creating superconducting diode-based rectifiers—devices that can convert AC to DC directly on the same chip 1 4 .
