Over the past decades, quantum physicists and engineers have developed numerous technologies that harness the principles of quantum mechanics to push the boundaries of classical information science.
Light is an excellent carrier of information used not only for classical communication technologies but also increasingly for quantum applications such as quantum networking and computing. However, ...
Specialized quantum memories will be required to achieve quantum speedups for data-intensive problems. Now, a proof-of-principle demonstration of such a quantum memory has been performed with a ...
The group of Prof. Xiao-Song Ma at Nanjing University has demonstrated the faithful teleportation from telecom photons to erbium-ion based quantum memory. The key elements for this achievement are the ...
Illustration of a nuclear frequency comb displaying single photons as visualized on a logarithmic scale from dark to bright colors, with brighter colors indicating instances of time where the stored ...
The past two decades have seen tremendous progress in the realization of photonic quantum memory devices 1,2,3,4, with a recent emphasis on intrinsically fiber-coupled devices suitable for ...
Physicists have used Doppler-shifted nuclear resonant absorbers to form a nuclear frequency comb, enabling a quantum memory in the notoriously difficult X-ray range. Light is an excellent carrier of ...
