What is Quantum Computing?
One can deal with several problems in a sequential way; one at a time. Quantum Computing is the ability to deal with all of these problem at the same time. In Quantum Physics, a particle can exist in two places at the same time, similarly, a Quantum Processor can process several inputs at the same time.
NTQC or The near-term quantum computers is the current target of many companies as a intermediate stage before reaching to the full ower Quantum Computers. NTQC are built with limited number of Qubits to reach the possible minimal error.
Riverlane
Riverlane builds ground-breaking software to unleash the power of quantum computers. Backed by leading venture-capital funds and the University of Cambridge, we develop software that transforms quantum computers from experimental technology into commercial products. We tease the highest possible performance out of quantum software to reach quantum advantage sooner. By making Riverlane’s software portable across technologies, early adopters don’t need to choose which technology to pursue. We go deep into the stack so that our hardware partners can focus on the physics and build better full-stack solutions. We work with the chemical, pharmaceutical and materials industries to improve algorithms and specify early killer applications of quantum computers. Our world-leading, multi-disciplinary team is based in the heart of Cambridge, UK. We work together to develop pioneering quantum software. Curious by nature, and optimistic in outlook, we have a razor-sharp focus on doing whatever it takes to get to useful quantum computing, sooner.

Quantum Metric
Digital products have to change faster than ever. But many companies aren’t built to move that fast. Data is siloed, teams take too long to prioritize, and impact is hard to quantify. That’s why we built Quantum Metric, a platform for Continuous Product Design, which is a fundamentally new approach that helps organizations deliver digital products that have greater impact, with speed and confidence.

Application of Quantum Computing
To simulate a chemical reaction, to break up an RSA encription, or to encode a large dataset for machine learning task, all of those jobs either take days, years or thousands of years, but with a Quantum Computer it could be couple of hours.
Cybersecurity
The first application uses advanced algorithms that a quantum computer can make practically possible. Peter Shor, professor at Massachusetts Institute of Technology and one of the pioneers of quantum computing, developed an algorithm for analyzing numbers using quantum computing. As currently known, numbers analysis is the main technique in data coding processes due to its difficulty. This algorithm, when applied, will reduce the time needed to analyze a number logarithmically. To be more specific, a regular algorithm for analyzing a number consisting of 15 digits needs 32,768 steps, and by using Shor’s algorithm, it will need 3,375 steps, but if the number consists of 20 digits, we will need 1,048,576 steps in comparison to the 800 steps of Shor’s algorithm.
This means that many cryptographic systems currently in place will be easy to crack in hours and that new systems and technologies will appear to save data. Shor’s algorithm alone poses a threat to public-key cryptographic systems such as RSA, which are used frequently in our daily activities when surfing the Internet and which mathematical defenses depend in part on how difficult it is to perform the opposite steps to derive the results of multiplying very large primes together. A report on quantum computing that was published in 2018 by the US National Academies of Sciences, Engineering, and Medicine predicted that a high-capacity quantum computer implementing Shor’s algorithm would be able to crack the executive version of RSA algorithm with a 1,024-bit key in less than one day.
Chemistry and Pharmaceutical Industry
Anika Chebrolu, a 14-year-old American girl of Indian origin, discovered the structure of a molecule that could distinguish and bind to the protein of the COVID-19 virus, which provided a basis for making drugs that could isolate and target the virus without harming the human body. What the clever girl did was use an algorithm that explored different chemical molecules and tested them with the targeted coronavirus protein, but this exploration process is usually expensive in terms of time and computation, and its operators always try to optimize it through various improvements to shorten time and cost.
