Concatenated Composite Pulses Beyond Local Residual-Error Preservation
Masamitsu Bando
Residual-error preservation (REP) provides a sufficient rule for constructing concatenated composite pulses that compensate multiple systematic errors. We show that local REP is no…
Concatenated Composite Pulses Applied to Liquid-State Nuclear Magnetic Resonance Spectroscopy
Masamitsu Bando, Tsubasa Ichikawa, Yasushi Kondo +3
The error-robust and short composite operations named ConCatenated Composite Pulses (CCCPs), developed as high-precision unitary operations in quantum information processing (QIP),…
Construction of Arbitrary Robust One-Qubit Operations Using Planar Geometry
Tsubasa Ichikawa, Jefferson G. Filgueiras, Masamitsu Bando +3
We show how to construct an arbitrary robust one-qubit unitary operation with a control Hamiltonian of , where is a Pauli matrix and is piec…
Concatenated composite pulses compensating simultaneous systematic errors
Masamitsu Bando, Tsubasa Ichikawa, Yasushi Kondo +1
In NMR experiments and quantum computation, many pulse (quantum gate) sequences called the composite pulses, were developed to suppress one of two dominant errors; a pulse length e…
Geometric Aspects of Composite Pulses
Tsubasa Ichikawa, Masamitsu Bando, Yasushi Kondo +1
Unitary operations acting on a quantum system must be robust against systematic errors in control parameters for reliable quantum computing. Composite pulse technique in nuclear ma…
Minimal and Robust Composite Two-Qubit Gates with Ising-Type Interaction
Tsubasa Ichikawa, Utkan Güngördü, Masamitsu Bando +2
We construct a minimal robust controlled-NOT gate with an Ising-type interaction by which elementary two-qubit gates are implemented. It is robust against inaccuracy of the couplin…
