Multi-particle entanglement manipulation under positive partial transpose preserving operations
Satoshi Ishizaka, Martin B. Plenio
We consider the transformation of multi-partite states in the single copy setting under positive-partial-transpose-preserving operations (PPT-operations) and obtain both qualitativ…
Carrier-Induced Magnetic Circular Dichloism in the Magnetoresistive Pyrochlore Tl2Mn2O7
H. Okamura, T. Koretsune, S. Kimura +4
Infrared magnetic circular dichloism (MCD), or equivalently magneto-optical Kerr effect, has been measured on the Tl2Mn2O7 pyrochlore, which is well known for exhibiting a large ma…
Ab initio Study of Valley Line on a Total-Energy Surface for Zone-Center Distortions of Ferroelectric Perovskite Oxides BaTiO3 and PbTiO3
Takeshi Nishimatsu, Takatoshi Hashimoto, Hiroshi Mizuseki +3
An ab initio structure optimization technique is newly developed to determine the valley line on a total-energy surface for zone-center distortions of ferroelectric perovskite oxid…
Bound entanglement provides convertibility of pure entangled states
Satoshi Ishizaka
I show that two distant parties can transform pure entangled states to arbitrary pure states by stochastic local operations and classical communication (SLOCC) at the single copy l…
Measured Quantum Fourier Transform of 1024 Qubits on Fiber Optics
Akihisa Tomita, Kazuo Nakamura
Quantum Fourier transform (QFT) is a key function to realize quantum computers. A QFT followed by measurement was demonstrated on a simple circuit based on fiber-optics. The QFT wa…
