Doing more with less: a path to efficient quantum computing

Building a useful quantum computer requires protecting fragile quantum information, but that protection can consume much of the machine’s hardware. Hengyun Zhou’s group at MIT and collaborators are developing ways to dramatically reduce that overhead. Across a series of recent studies, they have shown how to pack quantum information into efficient error-correcting codes, design more...

Famous double-slit experiment holds up when stripped to its quantum essentials

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of light. They also happen to confirm that Albert Einstein was wrong about this particular quantum scenario. The experiment in question is the double-slit experiment, which was first...

CUA Alumn Revolutionizes Baseball

When Aaron Leanhardt was a graduate student in physics at the Massachusetts Institute of Technology, he was part of a research team that cooled sodium gas to the lowest temperature ever recorded in human history. What his colleagues didn’t realize was that in the rare moments when Leanhardt wasn’t toiling away at the lab, he was moonlighting...

Intrinsic high-fidelity spin polarization of charged vacancies in hexagonal boron nitride

Spin defects in two-dimensional van der Waals materials have recently garnered significant interest, particularly for their potential as quantum sensing platforms due to their sub-nanometer proximity to the sample being probed. Among these, the negatively charged boron vacancy (VB-) centers in hexagonal boron nitride (hBN) have been actively studied for their room-temperature optical polarizability and...

Researchers make leap in quantum computing

Molecules haven’t been used in quantum computing, even though they have the potential to make the ultra-high-speed experimental technology even faster. Their rich internal structures were seen as too complicated, too delicate, too unpredictable to manage, so smaller particles have been used. But a team of Harvard scientists has succeeded for the first time in...
