Experimental Demonstration of Quantum State Multi-meter and One-qubit Fingerprinting in a Single Quantum Device
Jiangfeng Du, Ping Zou, Daniel K. L. Oi +4
We experimentally demonstrate in NMR a quantum interferometric multi-meter for extracting certain properties of unknown quantum states without resource to quantum tomography. It ca…
Perfect Transfer of Arbitrary States in Quantum Spin Networks
Matthias Christandl, Nilanjana Datta, Tony C. Dorlas +3
We propose a class of qubit networks that admit perfect state transfer of any two-dimensional quantum state in a fixed period of time. We further show that such networks can distri…
Mirror Inversion of Quantum States in Linear Registers
Claudio Albanese, Matthias Christandl, Nilanjana Datta +1
Transfer of data in linear quantum registers can be significantly simplified with pre-engineered but not dynamically controlled inter-qubit couplings. We show how to implement a mi…
A Generic Security Proof for Quantum Key Distribution
Matthias Christandl, Renato Renner, Artur Ekert
Quantum key distribution allows two parties, traditionally known as Alice and Bob, to establish a secure random cryptographic key if, firstly, they have access to a quantum communi…
Experimental demonstration of an efficient quantum phase-covariant cloning and its possible applications to simulating eavesdropping in quantum cryptography
Jiangfeng Du, Thomas Durt, Ping Zou +4
We describe a nuclear magnetic resonance (NMR) experiment which implements an efficient one-to-two qubit phase-covariant cloning machine(QPCCM). In the experiment we have achieved…
An experimental observation of geometric phases for mixed states using NMR interferometry
Jiangfeng Du, Ping Zou, Mingjun Shi +6
Examples of geometric phases abound in many areas of physics. They offer both fundamental insights into many physical phenomena and lead to interesting practical implementations. O…
