Clifford+V synthesis for multi-qubit unitary gates
Soichiro Yamazaki, Seiseki Akibue
We developed a general framework for synthesizing target gates by using a finite set of basic gates, which is a crucial step in quantum compilation. When approximating a gate in SU…
Existence of universal resource and uselessness of too entangled states for quantum metrology
Rina Miyajima, Yuki Takeuchi, Seiseki Akibue
We show (i) the existence of universal resource states for a certain class of linear Hamiltonians and (ii) the uselessness of highly entangled states for quantum metrology of linea…
Asymptotic Gate Count Bounds for Ancilla-Free Single-Qubit Synthesis with Arithmetic Gates
Kaoru Sano, Hayata Morisaki, Seiseki Akibue
We study ancilla-free approximation of single-qubit unitaries by gate sequences over Clifford+, where or their generalization. Let denote th…
Optimal ancilla-free Clifford+T synthesis for general single-qubit unitaries
Hayata Morisaki, Kaoru Sano, Seiseki Akibue
We propose two Clifford+ synthesis algorithms that are optimal with respect to -count. The first algorithm, called deterministic synthesis, approximates any single-qubit unit…
Duality of extremal quantum states in verification and data hiding
Seiseki Akibue, Yuki Takeuchi
Quantum state verification (QSV) and quantum data hiding (QDH) have so far been studied separately. QSV decides whether a given quantum state is close to the ideal one, with signif…
On the hardness of conversion from entangled proof into separable one
Seiseki Akibue, Go Kato, Seiichiro Tani
A quantum channel whose image approximates the set of separable states is called a disentangler, which plays a prominent role in the investigation of variants of the computational…
