Fingerprinting quantum noise Scientists from the University of Chicago and Purdue University propose a different method of understanding the effect of noise in quantum computers. Instead of trying to measure it directly, they created a 'fingerprint' of how the noise impacts a program run on the computer. “We wondered if there was a way to work with the noise, instead of against it,” sai... » read more

Improving batteries, ultra low-power photonic edge computing, SLAM, Tellurium for 2D semiconductors, and reservoir computing top the past week's technical papers. The focus on energy is critical as the edge buildout continues and more devices are connected to a battery, while research into new architectures and materials that will continue scaling and improve performance per watt continue at th... » read more

Bell state analyzer for spectrally distinct photons
By Technical Paper Link - 27 Mar, 2022 - Comments: 0

Abstract "We demonstrate a Bell state analyzer that operates directly on frequency mismatch. Based on electro-optic modulators and Fourier-transform pulse shapers, our quantum frequency processor design implements interleaved Hadamard gates in discrete frequency modes. Experimental tests on entangled-photon inputs reveal fidelities of ∼98% for discriminating between the |Ψ+⟩ and |Ψ−⟩... » read more

The resurrection of tellurium as an elemental two-dimensional semiconductor
By Technical Paper Link - 23 Mar, 2022 - Comments: 0

Abstract "The graphene boom has triggered a widespread search for novel elemental van der Waals materials thanks to their simplicity for theoretical modeling and easy access for material growth. Group VI element tellurium is an unintentionally p-type doped narrow bandgap semiconductor featuring a one-dimensional chiral atomic structure which holds great promise for next-generation electronic, ... » read more

Interferometer on chip Researchers at the University of Rochester developed an optical interferometer on a 2mm by 2mm integrated photonic chip that is capable of amplifying interferometric signals without a corresponding increase in extraneous noise. Interferometers merge two or more sources of light to create interference patterns that provide information able what they illuminate. “If y... » read more

Stopping interference in integrated photonics Researchers at EPFL and Purdue University combined integrated photonics and MEMS to develop an electrically driven optical isolator-on-a-chip that transmits light in only one direction. Optical isolators are useful to prevent reflected light from other components compromising or interfering with an on-chip laser’s performance. They are often c... » read more
