Where quantum computing is already delivering value


The field of quantum computing is developing quickly, and annealing models can perform calculations at speeds that are impossible to imagine. These hybrid quantum applications integrate the best features of both worlds, making them useful business tools. Differentiating between the gate and quantum annealing models is necessary to comprehend the value of quantum computing.

Qubits, which have the quantum property of superposition and enable the simultaneous manipulation of numerous combinations of states, are the foundation of quantum techniques. A variety of technologies can be used to create qubits. Quantum gates are used in place of conventional logic gates in gate models, and qubits can be controlled in annealing models to solve practical optimisation problems.

Edge of quantum annealing

Traditional computers have certain drawbacks, but annealing quantum computers can assist in solving significant issues. When solving optimization problems for 3D spin glasses and quantum simulations, annealing is more than three million times faster than conventional techniques. A business created a quantum hybrid program that, after considering 67 million possible outcomes, gave a solution in just 13 seconds.

Advantages of quantum computing

1. By selecting the lowest energy solution, the quantum annealing technique leverages quantum physics to optimize issues in the real world. This strategy combines the advantages of classical and quantum computing, making it perfect for Python-savvy developers who also have experience with quantum software development kits.

2. Bypassing the quantum annealing mechanism, developers can access quantum-classical hybrid solvers through the cloud. An annealing quantum computer receives workload from the front line of classical computing, which produces better outcomes and optimal solutions faster.

3. Error correction is another benefit of annealing; specifically, quantum annealing doesn’t require it. Since that noise can affect quantum computing, this may seem surprising. Yet, the quantum state can eventually reappear on an annealing quantum computer, allowing the search for the best solution to continue until it is successful.

4. Complex issues are handled by classical computers, while quantum computing is expanded by hybrid models. Future quantum computing will be hybrid, and optimization issues in both the public and private sectors will be best served by newly developed quantum systems.

The barrier to a quantum future

The constraints of the quantum state, the steep learning curve for developers, and the significant burden on developers are some of the difficulties faced by gate model quantum computers, which were once designed to replace binary computers. Nowadays, they are mostly used by researchers for fluid flow dynamics, differential equations, and research involving quantum chemistry. Since that gate model, quantum computers need to perform error correction, which is the main technical difficulty for quantum computing, they might never be more effective at solving optimization issues than annealing systems. Noisy Intermediate Scale Quantum (NISQ) computers are a moniker for some gate model systems that have abandoned error correction. According to D-Wave, it will be at least seven years until gate model quantum computers featuring trusted error correction are developed.

A partnership between computing technologies

Upcoming computing will continue to combine quantum and conventional techniques. The hype that classical computing will be replaced by quantum computing is untrue. 


Many applications of quantum annealing are showing promise, including traffic routing, missile defence, protein design issues, and financial portfolio management. Error correction and programming challenges might be resolved by the end of the decade, expanding the potential uses. With the support of the current generation of quantum annealing systems, almost all companies can now benefit from quantum-classical hybrid technology. They will also be getting ready for the inevitable quantum future at the same time.
