Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky

Temporal Jitter Analyzer And Analyzing Temporal Jitter

NIST Inventors
Joshua Bienfang
A temporal jitter analyzer analyzes temporal jitter and includes: a time delay controller; a time delay member; a delay measurement circuit; an edge generator in communication with the time delay member and that receives the delayed primary signal from the time delay member and produces a reference
