Violation of Heisenberg’s Measurement-Disturbance Relationship by Weak Measurements
... Heisenberg’s MDR we first experimentally characterize the bound of Eqs. (2) and (3). Lund and Wiseman discuss the limiting case of using perfectly weak measurements to characterize the system before the action of the MA [8]. However, in order to extract any information from this initial measurement, ...

Spin polarized transport in semiconductors – Challenges for
... Propagating surface plasmon polaritons (SPPs) are well-known to have both a subwavelength light confinement and long propagation lengths [1]. For this reason, their interaction with quantum emitters (QEs) has attracted great interest recently. The emergence of Strong Coupling (SC) when an ensemble o ...

Lecture 4 1 Unitary Operators and Quantum Gates
... We say that U is unitary if U † = U −1 . For example, rotations and reflections are unitary. Also, the composition of two unitary transformations is also unitary (Proof: U,V unitary, then (UV )† = V †U † = V −1U −1 = ...

Quantum Cryptography
... superposition of being on the path H and the path V, any quantum bit, or qubit, can be prepared in a superposition of its two logical states 0 and 1. • That means a qubit can store both 0 and 1 simultaneously. • In general a qubit can be written as a ...
