Quantum Computing use cases

These are early days where we can operate Quantum computer only at close to absolute zero using super-conducting materials. Only few companies with deep pockets have entered the space.

But the promise is huge as the recent news of quantum supremacy demonstrated.

· Quantum computing is still deep in the research and development phase, currently with only 2 commercially available offers (D-wave & IBM), but it remains a very promising technology, mostly due to its expected huge computing capacities and the use cases it promises.

· Quantum computing is strongly linked to quantum mathematical properties, so use cases are linked to physics, chemicals, materials, especially around real-time parallel computing for very complex systems simulation. At present, only around a dozen use cases are in proof of concept stage, essentially on the D-Wave technology.

· The quantum computing market will enjoy huge growth in the coming years, and the ones who benefit from this will be the participants and the countries that host technology clusters which enable maximum collaboration between state-funded research, start-ups, major companies and venture capital.

Quantum computing Use Cases under adoption.

The following use cases are based on the first quantum computer to be put on the market, the D-Wave 2000Q, produced by the Canadian company D-wave with a catalog price of 15 million CAN$.

Use cases under development

1. Volkswagen — Daily movement simulation of 10,000 taxis in a large city based on their GPS positions

2. Lockheed Martin- Optimize and shorten validation procedures from 8 months to 6 weeks using embedded software.

3. Accenture and quantum firm 1Qbit collaborated with Biogen — Screening of molecules to identify additional uses of existing molecules and of their combinations

4. Google and NASA — Exoplanet detection from analysis of telescopic observations, as well as optimization and planning problems.

5. Q Branch — High performance analytics to validate assumptions about the results of the last US presidential election.

6. DENSO — Optimization of the operations of a fleet of electrical delivery vehicles.

Potential Use cases of Quantum Computing in different business segments

1. Finance -Quantum computing can allow faster and more complex “Monte Carlo” simulations, in areas such as trading, trajectory optimization, market instability, price optimization and hedging strategies.

2. Healthcare- Quantum computing could be used to accelerate the sequencing of DNA genes, the optimization of treatment in radiotherapy and better and faster detection of brain tumors.

3. Manufacturing -One of the most promising uses of quantum computing is the simulation and discovery of the properties of new materials and active products (for chemistry and pharmacy), through the simulation of atomic interactions. Projects based around this notion are in progress at Dow Chemicals and at Airbus.

4. Weather forecasting - The computing capabilities, the management of the complexity of the assumptions and the speed of the predictions of the calculations of quantum systems could be significant.

5. Utilities and energy- Quantum computing simulation capacities could be used to improve oil exploration, and BP has a project ongoing on this topic. Dubai Electricity is experimenting around distribution and optimization of the water and electricity networks.

6. Transportation -The management and optimization of traffic (road, rail, air, etc.), the operation of vehicle fleets and the management of autonomous vehicles are promising fields where the inherent qualities of Quantum could well express their potential. Several companies are evaluating this around the optimization of filling of airline fleets in near real time and in a global way.

7. Cyber security- Theoretically Cyber security is where quantum computing could cause the biggest disruption as it could be used to break the protection algorithms of the public key infrastructures (PKI). However, it could also be used to protect, by creating a new PKI system with quantum algorithms. The CGHQ (the British ANSSI) and the NSA have acquired a D-Wave machine to explore those issues.
