The measurement of a quantum state poses a unique challenge for experimentalists. Recently, the technique of ‘direct measurement’ was proposed for characterizing a quantum state in situ through ...

The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...

The noncontacting angular position sensor (NCAPS) Thin Profile 7000 series unit measures less than 8 mm thick without housing. In a fully sealed package, it provides true 360° absolute rotary position ...

Incorporating patent-pending technology, the Non-Contacting Angular Position Sensor (NCAPS) combines transceiver technology and digital processing techniques with durable materials in a package size ...

Six photons: physicists in China have entangled photons in terms of polarization, position and orbital angular momentum. (Courtesy: iStock/CopterAnansak) Physicists in China have fully entangled 18 ...
