Spintronics is an emerging field of nanoscale electronics  whose central theme is the active manipulation of spin degrees of freedom of charge carriers in solid-state systems, in addition to their electronic charge used in traditional semiconductor electronics. Spintronics or spin electronics in contrast to conventional electronics uses the spin of electrons …

Modern cryptography being used extensively for securing our internet payments, banking transactions, emails and even phone conversations use cryptographic algorithms based on public-key encryption, which is considered to be secure against attacks from modern computers.   The development of quantum computers once seen as a remote theoretical possibility is now …

The utility of Modern high frequency Radars have become degraded due to  innovation in stealth that resulted include unusual shapes that deflect radar waves—like the US B-2 bomber’s “flying wing” design (above)—as well as carbon-based materials and novel paints.  China and Russia have since gotten stealth aircraft of their own, …

In March 2018,  Google unveiled Bristlecone, a new quantum computing chip with 72 quantum bits, or qubits—the fundamental units of computation in a quantum machine beating the  previous record holder of 50-qubit processor  by IBM. The goal of the Google Quantum AI lab is to build a quantum computer that can be …

The International Data Corp. reported that the global datasphere contained 33 zettabytes, or 33 trillion gigabytes, in 2018. By 2025, they expect that number to grow to 175 zettabytes. 175 zettabytes of information stored on DVDs would fill enough DVDs to circle Earth 222 times. In classical computing, information is stored …

In quantum computing, a qubit or quantum bit is the basic unit of quantum information—the quantum version of the classical binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples …

Trions are what scientists call “quasiparticles,” bundles of energy, electric charge and spin that zoom around inside semiconductors.   Trions were first observed in quantum wells in 1993 and shortly thereafter in GaAs-AlGaAs quantum wells. Trions were were predicted and found in the photoluminescence and absorption spectra of various optically …

The Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these objects to connect and exchange data. Each thing is uniquely identifiable through its embedded computing system but is able to inter-operate within the …

Quantum information is the enabling factor behind a number of emerging technologies that many physicists expect to have a huge impact on society in future: powerful quantum computers, (almost) perfectly secure quantum cryptography and the quantum internet that will distribute these capabilities round the planet. Quantum cryptography is an emerging technology …

Quantum sensing uses some nonintuitive properties of nature to measure things like time, magnetic fields, gravity, or acceleration. Quantum sensing has become a distinct and rapidly growing branch of research within the area of quantum science and technology, with the most common platforms being spin qubits, trapped ions and flux qubits. …
