Quantum Computer Using Neutral Atoms

Shuta NAKAJIMA

In recent years, optical tweezer arrays of neutral atoms have attracted much attention as a platform for implementing quantum computers. The neutral atom quantum computers are a promising candidate for fault-tolerant quantum computation due to their high controllability and scalability based on the technique of reconfigurable optical tweezers array and the use of Rydberg states to realize a two-qubit gate between two distant atoms in the optical tweezers. In this paper, we will give an overview of the neutral atom quantum computer and its technical issues and introduce our research using atoms in an optical tweezer array.In recent years, optical tweezer arrays of neutral atoms have attracted much attention as a platform for implementing quantum computers.

Alkaline Atoms Held with Optical Tweezers

Alkaline Atoms Held with Optical TweezersThree separate groups demonstrate the trapping of two-electron atoms in arrays of optical tweezers, opening up new opportunities for quantum simulation and many-body studies.by Antoine Browaeys * Q uantum technology is a very active field of research, in which the resources of quantum physics, such as superposition and entanglement, are utilized to perform tasks that are classically hard or impossible.The promises from this field are many, ranging from quantum computation of difficult mathematical problems to the building of more sensitive sensors.But to realize these possibilities, experimentalists have to engineer well-controlled quantum systems made of many individual elements that can interact with each other.Among the many platforms currently studied (ions, photons, electron spins, to name a few), neutral atoms have the advantage that they can be manipulated with high accuracy, and they are scalable in the sense that many thousands of atoms can be controlled.New experiments by three separate groups haveAlkaline Atoms Held with Optical TweezersThree separate groups demonstrate the trapping of two-electron atoms in arrays of optical tweezers, opening up new opportunities for quantum simulation and many-body studies.by Antoine Browaeys * Q uantum technology is a very active field of research, in which the resources of quantum physics, such as superposition and entanglement, are utilized to perform tasks that are classically hard or impossible.The promises from this field are many, ranging from quantum computation of difficult mathematical problems to the building of more sensitive sensors.But to realize these possibilities, experimentalists have to engineer well-controlled quantum systems made of many individual elements that can interact with each other.Among the many platforms currently studied (ions, photons, electron spins, to name a few), neutral atoms have the advantage that they can be manipulated with high accuracy, and they are scalable in the sense that many thousands of atoms can be controlled.New experiments by three separate groups have
