Quantum cryptography (QC) or Quantum key distribution (QKD) are assumed hackproof but its implementations have vulnerabilities

Quantum computers could undermine almost all of the encryption protocols that we use today. Though quantum computers are still quite some way from being practical, usable machines, once they become so, we could be looking at a whole new world when it comes to online privacy — one in which …

AI enabled Intelligent Satellite Networks

Satellite communication can provide many benefits and complement terrestrial networks. They can provide service continuity, to provide network access over uncovered and under-covered areas. They can provide backup or service ubiquity, to ameliorate the network availability in cases of temporary outage or destruction of a ground network due to disasters. …

Quantum computer threat on digital infrastructure requires Quantum proof cryptography, NIST standardizing post-quantum cryptographic algorithms

Cryptography is based on mathematical problems that are extremely difficult for conventional computers to solve or avoid. However, the quantum machines of the future will be able to do so more easily, making our protection systems obsolete. For now, quantum computers are not powerful or advanced enough to defeat today’s …

Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

Electric Propulsion based on Iodine Fuel will enable Moon and other near Earth objects missions to deorbiting, rendezvous, and satellite maintenance mission

Propulsion systems can be classified based on their dependence on the onboard power: electric and non-electric systems. Electric propulsion systems are mainly classified into resistojet, electrospray, ion, Hall and pulsed plasma systems, and they actively require on-board power for their operation, while the non-electric propulsion systems can be classified into …

Attosecond lasers

The laser has revolutionized many areas of science and society, providing bright and versatile light sources that transform the ways we investigate science and enables trillions of dollars of commerce. In manufacturing, for example, robotic lasers have been programmable in a way that mechanical cutting tools had not been, with …

Microsatellite and Nanosatellite constellations require new micro propulsion technologies for autonomous civil and military missions

Traditionally the launched satellites were Large ( Mass >1000 Kgs) and Medium satellites (500 to 1000 Kgs) which were high-performance, multifunctional with long lives which required larger rockets with greater thrust and expensive to launch, and took long development times. Only large commercial players and government organizations could afford to …

Silicon Waveguides critical element of silicon photonics in communications, interconnects, and biosensors

Silicon photonics uses photons to detect processes and transmit information more efficiently than electrical signals, and yet have low manufacturing costs as a result of using conventional silicon-integrated-circuit processes. The same processes have made transistors, microchips, and integrated circuits from silicon to be small, affordable, and energy-efficient devices that could …

Nonlinear photonics or optics key enabling technology for imaging, high-speed data communication and optical computing

Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. Nonlinear optics (NLO) is the branch of optics that describes the behavior of light in nonlinear media, that is, media in …

Materials for nonlinear integrated photonics

Nonlinear optics (NLO) is the branch of optics that describes the behavior of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. The nonlinearity is typically observed only at very high light intensities (values of the …
