Teleportation with a Mixed State of Four Qubits and the Generalized Singlet Fraction
Abstract Recently, an explicit protocol E0 for faithfully teleporting arbitrary two-qubit states using genuine four-qubit entangled states was presented by us [Phys. Rev. Lett. 96, 060502 (2006)]. Here, we show that E0 with an arbitrary four-qubit mixed state resource Ξ is equivalent to a generalized depolarizing bichannel with probabilities given by the maximally entangled components of the re...
متن کاملThe Relativistic Effects on the Violation of the Bell's Inequality for Three Qubit W State
In this paper we are going to calculate the correlation function and Bell'sinequality for three qubit W state under the Lorentz transformations. This survey is basedon the introduction of two different expressions of spin observable were presented byLee-Young and Kim-Son.
متن کاملImplementing generalized measurements with superconducting qubits
We describe a method to perform any generalized purity-preserving measurement of a qubit with techniques tailored to superconducting systems. First, we consider two methods for realizing a two-outcome partial projection: using a thresholded continuous measurement in the circuit QED setup and using an indirect ancilla qubit measurement. Second, we decompose an arbitrary purity-preserving two-out...
متن کاملBounding the entanglement of N qubits with only four measurements
Quantum-mechanical systems can be used for real-world applications of significant importance, including quantum information processing [1,2], quantum cryptography [3], and quantum metrology [4]. Many of these applications require entanglement between more than two parties; see, e.g., [1,2]. Such systems also allow us to probe the transition from quantum to classical behaviors in increasingly co...
متن کاملFast accurate state measurement with superconducting qubits.
Faster and more accurate state measurement is required for progress in superconducting qubit experiments with greater numbers of qubits and advanced techniques such as feedback. We have designed a multiplexed measurement system with a bandpass filter that allows fast measurement without increasing environmental damping of the qubits. We use this to demonstrate simultaneous measurement of four q...
