Energy cost of entanglement extraction: Alice and Bob have access to two parts of a quantum system in an entangled state |Ω〉AB with Hamiltonian HAB. Using local operations and classical communication (LOCC), they extract m EPR pairs into their ancillary systems A′ and B′, leaving the phy...
University of Toronto physics students James Bateman (left) and Lee Rozema (right) led a study which successfully measured multiple photons in an entangled NOON state. The work paves the way for great advances in using quantum states to enable the next generation of ultra-precise measurement tech...
We successfully inject an entangled state into a Mach–Zehnder light-pulse interferometer with directly observed sensitivity 1.7−0.5+0.5 dB below the standard quantum limit. The combination of particle delocalization and entanglement in our approach may influence developments of enhanced inertial ...
We present a simple scheme to generate a maximally entangled state of two four-level Rydberg atoms with a nonresonant cavity by cavity-assisted collisions. By using this scheme, the maximally entangled state of two N-level (N > 4) Rydberg atoms can also be obtained. During the passage of ...
This thesis explores the use of entangled states in quantum computation and quantum information science. Entanglement, a quantum phenomenon with no classical counterpart, has been identified as an important and quantifiable resource in many areas of theoretical quantum information science, including quantum...
29 (Xinhua) -- Over the past week pressure has been mounting on South Korean President Park Geun-hye, who has been suspected of letting her longtime friend to intervene in state affairs. Park's approval rating has fallen to 17 percent, the lowest since her inauguration in 2013, from 25 ...
This creates an entangled state that can detect and correct bit-flip errors. from qiskit import QuantumCircuit, QuantumRegister # Define the bit-flip code circuit def bit_flip_code(): # Create a quantum register with 3 qubits qr = QuantumRegister(3) circuit = QuantumCircuit(qr) # Encoding ...
an article published by Washington Post on Aug. 22 last year, with domestic debates in the U.S. over immigration increasingly driven by racialized resentment, anti-immigrant sentiment and entangled with domestic political battles, U.S. policymakers are more inclined to use techniques like force ...
Zein networks exhibited unique viscous behaviour (in line with that of an entangled polymer solution), in each amplitude, frequency and temperature sweeps, however only when freshly formed. The results suggest that the bonds and interactions responsible for strengthening zein networks need at least 24...
