Entangling unstable optically active matter qubits
Yuichiro Matsuzaki, Simon C. Benjamin, Joseph Fitzsimons
In distributed quantum computation, small devices composed of a single or a few qubits are networker together to achieve a scalable machine. Typically there is an optically active…
Necessity of Superposition of Macroscopically Distinct States for Quantum Computational Speedup
Akira Shimizu, Yuichiro Matsuzaki, Akihisa Ukena
For quantum computation, we investigate the conjecture that the superposition of macroscopically distinct states is necessary for a large quantum speedup. Although this conjecture…
Quantum Zeno effect with a superconducting qubit
Yuichiro Matsuzaki, Shiro Saito, Kosuke Kakuyanagi +1
Detailed schemes are investigated for experimental verification of Quantum Zeno effect with a superconducting qubit. A superconducting qubit is affected by a dephasing noise whose…
Distributed quantum computation with arbitrarily poor photon detection
Yuichiro Matsuzaki, Simon C. Benjamin, Joseph Fitzsimons
In a distributed quantum computer scalability is accomplished by networking together many elementary nodes. Typically the network is optical and inter-node entanglement involves ph…
