Circuit Optimization for Universality Transformation
Yasuaki Nakayama, Yuki Takeuchi, Seiseki Akibue
It is known that a computationally universal gate set can be transformed to a strictly universal one using one maximally imaginary state an…
Uniqueness of imaginarity-assisted transformation from computationally universal to strictly universal quantum computation
Yasuaki Nakayama, Yuki Takeuchi, Seiseki Akibue
The computational universality with an elementary gate set can be transformed to the strict universality by using a maximally imaginary state and some non-…
Anonymous quantum sensing robust against state preparation errors
Hiroto Kasai, Seiichiro Tani, Yasuhiro Tokura +1
Networked quantum sensors have several applications such as the mapping of magnetic fields. When the magnetic fields are biomagnetic ones, i.e., they contain some private informati…
Quantum algorithm for unstructured search of ranked targets
Kota Tani, Shunji Tsuchiya, Seiichiro Tani +1
Grover's quantum algorithm can find a marked item from an unstructured database faster than any classical algorithm, and hence it has been used for several applications such as cry…
