Multiverse says new algorithm increases value of NISQ machines
Multiverse Computing, a firm heavily focused on developing financial sector algorithms and applications for quantum computing, said it has a new algorithm that allows today’s Noisy Intermediate-Scale Quantum (NISQ) machines to function as a “quantum-based calculators” for complex financial calculations.
The new algorithm leverages “continuous variables” which can’t be counted because they can take on an unlimited number of values between the lowest and highest points of measurements. The algorithm’s efficiency is derived from the combination of two approaches to enable continuous optimization – encoding qubits with three continuous variables and quantum state tomography. The algorithm makes use of all the powerful features of quantum computers: entanglement, superpositions, and now continuous encoding, Multiverse stated.
The company has issued a new paper, titled “Variational Quantum Continuous Optimization: a Cornerstone of Quantum Mathematical Analysis,” that explains and demonstrates this advancement. The algorithm is designed to run on programmable quantum computers, and was tested on a simulator. It could be used to help quantum computers run complex calculations used by scientists on a daily basis, including derivatives, partial differential equations, Fourier analysis and other calculations which currently require specialized software to complete, according to Multiverse.
Multiverse offered one example of how the new algorithm could be employed in a real-world scenario, saying it could be used to optimize operations in a factory by taking into account multiple continuous variables, such as temperature, humidity, air pressure and other constantly changing conditions.
But key to the algorithm’s benefits is its ability to derive value from NISQ machines at a time when quantum computer developers are under increasing pressure to how prospective customers that they do not have to wait decades to realize benefits from quantum computers.
“Our research shows that we can transform today’s Noisy Intermediate-Scale Quantum (NISQ) devices into advanced quantum-based ‘calculators’ that are able to do very complex calculations with very few qubits and limited error correction and provide value now,” said Román Orús, co-founder and Chief Scientific Officer at Multiverse. n“These simulations are at least comparable to the best classical computers today and will only improve as quantum computing performance increases.”
He added, “We will still be able to use these types of algorithms once we have fault-tolerant computers. Quantum computers with more qubits and advanced error correction will only increase the accuracy, quality and the speed of the solution.”
