Imagine if all our scientific theories and models told us only about averages: if the best weather forecasts could only give you the average daily amount of rain expected over the next month, or if astronomers could only predict the average time between solar eclipses.
At the core of quantum computing is the qubit. The best ones have a few defining traits, and scientists are looking to everything from lasers to Russian diamonds to help refine the best qubits for the next generation of quantum computing.
In the world of quantum computing, diamonds might be an...
Here’s a little-known fact about quantum computing: It sounds remarkably warm.
Notes from Woodbridge Hall
This year I will celebrate my thirty-eighth year as a New Haven resident. I have seen many exciting changes come to the Elm City, including wonderful restaurants, stores, and arts and cultural opportunities. In recent years, a number of entrepreneurs have recognized what many of us have long known—...

The “spooky physics” of the quantum world has long been marked by two key ideas: the idea of superposition, meaning that a quantum particle can exist in multiple states simultaneously, and the idea of randomness, meaning that it’s impossible to predict when certain quantum transitions will take...
An experiment caught a quantum system in the middle of a jump — something the originators of quantum mechanics assumed was impossible.
Yale researchers have figured out how to catch and save Schrödinger’s famous cat, the symbol of quantum superposition and unpredictability, by anticipating its jumps and acting in real time to save it from proverbial doom. In the process, they overturn years of cornerstone dogma in quantum physics...
Quantum optomechanical effects have been observed for the first time using a liquid—superfluid helium—confined in an optical cavity.

Quantum computers require controlled encoding to protect computations from environmental noise. Two experiments have achieved such encoding using what are known as infinite-dimensional quantum systems.

One of the key concepts in quantum physics is entanglement, in which two or more quantum systems become so inextricably linked that their collective state can’t be determined by observing each element individually. Now Yale researchers have developed a “universal entangler” that can link a variety...
