A New Option for Neutral-Atom Quantum Computing

Neutral atom quantum register.

We demonstrate the realization of a quantum register using a string of single neutral atoms which are trapped in an optical dipole trap. The atoms are selectively and coherently manipulated in a magnetic field gradient using microwave radiation. Our addressing scheme operates with a high spatial resolution, and qubit rotations on individual atoms are performed with 99% contrast. In a final read...

Computing light masks in neutral atom lithography

In neutral atom lithography, a collimated beam of atoms is sent through a region of standing light waves created by interfering laser beams. The intensity distribution of the light field modulates the density distribution of the atoms transversal to the beam direction. The atomic beam materializes on a substrate, and the atoms are deposited in a pattern which mimics the intensity distribution o...

A New Model Representation for Road Mapping in Emerging Sciences: A Case Study on Roadmap of Quantum Computing

One of the solutions for organizations to succeed in highly competitive markets is to move toward emerging sciences. These areas provide many opportunities, but, if organizations do not meet requirements of emerging sciences, they may fail and eventually, may enter a crisis. In this matter, one of the important requirements is to develop suitable roadmaps in variety fields such as strategic, ca...

Demonstration of a neutral atom controlled-NOT quantum gate.

We present the first demonstration of a CNOT gate between two individually addressed neutral atoms. Our implementation of the CNOT uses Rydberg blockade interactions between neutral atoms held in optical traps separated by >8 microm. Using two different gate protocols we measure CNOT fidelities of F=0.73 and 0.72 based on truth table probabilities. The gate was used to generate Bell states with...
