Most quantum computing technologies rely on the ability to produce, manipulate and detect non-classical states of light. Non-classical states are quantum states that cannot directly be produced using conventional sources ...
Sitting on a beach looking out to sea, it may seem unusual to spot one of the world's largest animals swimming in shallow coastal 30-foot-deep waters. But each winter, female southern right whales migrate thousands of miles ...
