Designing a Million-Qubit Quantum Computer Using Resource Performance Simulator
Muhammad Ahsan, Rodney Van Meter, Jungsang Kim
The optimal design of a fault-tolerant quantum computer involves finding an appropriate balance between the burden of large-scale integration of noisy components and the load of im…
A Regular Representation of Quantum Circuits
Alexandru Paler, Ilia Polian, Kae Nemoto +1
We present a quantum circuit representation consisting entirely of qubit initialisations (I), a network of controlled-NOT gates (C) and measurements with respect to different bases…
Interoperability in encoded quantum repeater networks
Shota Nagayama, Byung-Soo Choi, Simon Devitt +2
The future of quantum repeater networking will require interoperability between various error correcting codes. A few specific code conversions and even a generalized method are kn…
Floquet-Magnus Theory and Generic Transient Dynamics in Periodically Driven Many-Body Quantum Systems
Tomotaka Kuwahara, Takashi Mori, Keiji Saito
This work explores a fundamental dynamical structure for a wide range of many-body quantum systems under periodic driving. Generically, in the thermodynamic limit, such systems are…
Quantum feedback amplification
Naoki Yamamoto
Quantum amplification is essential for various quantum technologies such as communication and weak-signal detection. However, its practical use is still limited due to inevitable d…
Analysis of Quantum Network Coding for Realistic Repeater Networks
Takahiko Satoh, Kaori Ishizaki, Shota Nagayama +1
Quantum repeater networks have attracted attention for the implementation of long-distance and large-scale sharing of quantum states. Recently, researchers extended classical netwo…
Spin Amplification with Inhomogeneous Broadening
Suguru Endo, Yuichiro Matsuzaki, William J. Munro +1
A long-lived qubit is usually well-isolated from all other systems and the environments, and so is not easy to couple with measurement apparatus. It is sometimes difficult to imple…
Si nuclear spins as a resource for donor spin qubits in silicon
Gary Wolfowicz, Pierre-Andre Mortemousque, Roland Guichard +4
Nuclear spin registers in the vicinity of electron spins in solid state systems offer a powerful resource to address the challenge of scalability in quantum architectures. We inves…
Entanglement-assisted quantum feedback control
Naoki Yamamoto, Tomoaki Mikami
The main advantage of quantum metrology relies on the effective use of entanglement, which indeed allows us to achieve strictly better estimation performance over the standard quan…
Interaction of Strain and Nuclear Spins in Silicon: Quadrupolar Effects on Ionized Donors
David P. Franke, Florian M. Hrubesch, Markus Künzl +5
The nuclear spins of ionized donors in silicon have become an interesting quantum resource due to their very long coherence times. Their perfect isolation, however, comes at a pric…
Statistical hypothesis testing by weak-value amplification: Proposal and evaluation
Yuki Susa, Saki Tanaka
We study the detection capability of the weak-value amplification on the basis of the statistical hypothesis testing. We propose a reasonable testing method in the physical and sta…
