BB84 Protocol: Quantum Key Distribution for Unbreakable Communication

In the realm of secure communication, the BB84 protocol stands out as a groundbreaking achievement in the field of quantum key distribution (QKD). Proposed by Charles Bennett and Gilles Brassard in 1984, the BB84 protocol leverages the principles of quantum mechanics to enable the exchange of cryptographic keys in a manner that is theoretically immune… Continue reading BB84 Protocol: Quantum Key Distribution for Unbreakable Communication

D-Wave Quantum Inc., a company in quantum computing, has commended U.S. policymakers for incorporating a quantum pilot program into the National Defense Authorization Act (NDAA). This landmark legislation, signed into law by President Biden on December 22, 2023, establishes a program focused on near-term quantum computing applications to address challenges faced by the Department of Defense (DOD) and the Armed Forces. D-Wave, known for its quantum computing systems, software, and services, applauds the bipartisan effort, emphasizing the importance of leveraging quantum technologies to enhance national security.

The quantum pilot program outlined in the NDAA aims to test, evaluate, and implement quantum and quantum-hybrid applications to address pressing issues in defense, military, and national security operations. Notably, the program encourages the use of annealing quantum computing and quantum-hybrid technologies. It also emphasizes the need to build and strengthen collaborations between the DOD, academic institutions, small businesses, and non-traditional defense contractors.

D-Wave, as the world’s first commercial supplier of quantum computers, is well-positioned to contribute to the program. The company has already developed demonstrations, proof of concepts (POCs), and applications for various governments and businesses globally. Examples include optimizing cargo pier operations at the Port of Los Angeles, last-mile resupply applications for the Australian Army, and initiatives for carbon emission reduction and tsunami evacuation route optimization in Japan.

Dr. Alan Baratz, CEO of D-Wave, expressed appreciation for Congress and the Administration, stating that the quantum pilot program accelerates the use of quantum solutions for critical challenges faced by the DOD and the military. He highlighted the bipartisan nature of this action and emphasized D-Wave’s readiness to collaborate with the government to advance the program.

The inclusion of a quantum pilot program in the NDAA marks a pivotal moment in the integration of quantum computing into U.S. national security efforts. D-Wave Quantum Inc.’s commendation reflects the commitment of the quantum industry to collaborate with government agencies in addressing complex challenges. As the program unfolds, it is anticipated to usher in a new era of technological innovation and strategic solutions for the defense and security landscape.

Is optical computing the future?

To directly answer the question of what optical computing is? Optical computing refers to the use of light or photons to perform computation instead of traditional electronic means. It holds promise for faster and more efficient processing. How can one build logic gates and complex circuits using light? To achieve any logic gate, such as… Continue reading Is optical computing the future?

Is a quantum era even possible?

In times when the gaps between nodes from TSMC or Samsung are growing larger and the performance or efficiency gains are becoming increasingly marginal, many are not asking whether quantum computers will replace the dying Moore’s Law but only when. But is this technically possible to entangle enough qubits to satisfy our constant hunger for… Continue reading Is a quantum era even possible?

Superconducting electrode controls spin waves in a magnet

Placing a superconducting electrode on top of a thin magnet makes it possible to manipulate and control so-called “spin waves” within the magnet simply by changing the electrode’s temperature. This result, from quantum physicists at Delft University of Technology in the Netherlands, could advance the development of spintronics devices, which exploit the spin of an… Continue reading Superconducting electrode controls spin waves in a magnet

What would happen if communication systems broke down?

“A sight never to be forgotten.” n “Heaven became illuminated.” n “Nothing could exceed the grandeur and the beauty.” n These are just some of the phrases used by eyewitnesses to describe the remarkable aurora that danced over much of the globe for three special nights in early September 1859. Visible at unprecedented low latitude… Continue reading What would happen if communication systems broke down?
