Control systems are ubiquitous, and as essential as they are easy to overlook. For instance, turning the dial on a thermostat feels as trivial as moving a piece on a board game, but this control system is actually quite complex. Electricity is used to continuously compress a gas outside the home, so that the air will cool as it re-expands until the molecules inside are moving as slow as ...

A big part of the burgeoning science of quantum computation is reliably storing and processing information in the form of quantum bits, or qubits.  One of the obstacles to this goal is the difficulty of preserving the fragile quantum condition of qubits against unwanted outside influence even as the qubits interact among themselves in a programmatic way. 

Spin qubits are ...

Physicists use theoretical and experimental techniques to develop explanations of the goings-on in nature. Somewhat surprisingly, many phenomena such as electrical conduction can be explained through relatively simplified mathematical pictures — models that were constructed well before the advent of modern computation. And then there are things in nature that push even the limits of high performance computing and sophisticated ...

JQI graduate student Shuo Sun has won the Maiman Outstanding Student Paper Competition at CLEO, held annually in May. Sun's paper was titled "A solid-state spin-photon transistor." According to the website, "This competition was established in 2008 in memory of Theodore Maiman and in acknowledgement of his amazing invention, the first working laser, and his other outstanding contributions to optics and ...
