Lattice patch structure for fixed-frequency transmon quantum computer with high-fidelity CNOT gates
Chanpyo Kim, Jeongsoo Kang, Younghun Kwon
Superconducting transmon processors represent a leading platform for large-scale quantum computing due to their high gate fidelities and scalability. However, conventional qubit-co…
Construction of new type of CNOT gate using cross-resonance pulse in the transmon-PPQ system
Jeongsoo Kang, Younghun Kwon
The transmon, known for its fast operation time and the coherence time of tens of microseconds, is the most commonly used qubit for superconducting quantum processors. However, it…
Implementation of Magic State Injection within Heavy-Hexagon Architecture
Hansol Kim, Wonjae Choi, Younghun Kwon
The magic state injection process is a critical component of fault-tolerant quantum computing, and numerous studies have been conducted on this topic. Many existing studies have fo…
New Design of three-qubit system with three transmons and a single fixed-frequency resonator coupler
Jeongsoo Kang, Chanpyo Kim, Younghun Kim +1
The transmon, which has a short gate time and remarkable scalability, is the most commonly utilized superconducting qubit, based on the Cooper pair box as a qubit or coupler in sup…
