Latest Breakthroughs in Quantum Computing

IBM has made a ground breaking announcement in the field of quantum computing, published on the cover of the prestigious scientific journal Nature. The company has successfully demonstrated that quantum computers can deliver accurate results on a scale surpassing classical approaches, using over 100 qubits.

One of the fundamental goals of quantum computing is to efficiently simulate components of materials that classical computers struggle to handle. This capability is crucial for tackling complex challenges such as designing more effective fertilizers, developing advanced batteries, and discovering new medicines. However, the inherent noise and errors in today’s quantum systems have posed significant obstacles. Quantum bits, or qubits, are highly sensitive and prone to disturbances from their environment.

In their recent experiment, the IBM team showcased that a quantum computer (IBM Quantum Datacenter in Europe) can outperform leading classical simulations by effectively learning from and mitigating errors in the system. The team utilized the IBM Quantum ‘Eagle’ quantum processor, which consists of 127 superconducting qubits on a chip. They generated large entangled states that simulate the behavior of spins in a material model and accurately predicted properties such as magnetization.

To validate the accuracy of the quantum modeling, a team of scientists at UC Berkeley conducted simultaneous simulations on advanced classical computers at Lawrence Berkeley National Lab’s National Energy Research Scientific Computing Center (NERSC) and Purdue University. As the complexity of the model increased, the quantum computer continued to deliver precise results, thanks to advanced error mitigation techniques. In contrast, the classical computing methods eventually struggled to match the performance of the IBM Quantum system.

Darío Gil, Senior Vice President and Director of IBM Research, expressed the significance of this achievement, stating, “This milestone is a significant step in proving that today’s quantum computers are capable, scientific tools that can be used to model problems that are extremely difficult – and perhaps impossible – for classical systems.” He emphasized that quantum computers are entering a new era of utility, where they can tackle complex problems beyond the reach of classical systems.

Building upon this breakthrough, IBM announced its commitment to developing utility-scale processors across its IBM Quantum systems, both on the cloud and at partner locations. Over the next year, these systems will feature a minimum of 127 qubits, offering increased computational power and improved coherence times with lower error rates. IBM Quantum aims to establish a new threshold in the industry, enabling quantum computers to serve as scientific tools for exploring a new realm of problems that classical systems may never solve.

Jay Gambetta, IBM Fellow and Vice President of IBM Quantum, invited clients, partners, and collaborators to leverage these utility-scale processors and push the limits of today’s quantum systems. He highlighted the potential for extracting real value from quantum computing, as IBM progresses its mission to make this technology widely accessible.

IBM Quantum users worldwide will have access to utility-scale processors with over 100 qubits. This development enables researchers and industry leaders to explore advanced quantum algorithms and address their most challenging problems. The recent IBM Quantum Spring Challenge provided over 2,000 participants with access to utility-scale processors as they delved into dynamic circuits, facilitating the exploration of more sophisticated quantum algorithms.

Various sectors, including healthcare and life sciences, high energy physics, materials science, and optimization, are actively collaborating with IBM to harness the value of quantum computing. Prominent organizations such as Cleveland Clinic, Moderna, CERN, DESY, Boeing, Bosch, The University of Chicago, Oak Ridge National Lab, ExxonMobil, RIKEN, E.ON, and Wells Fargo are working alongside IBM to explore the potential applications of quantum computing in their respective fields.

As IBM continues to advance its quantum technology stack, these collaborative efforts hold the promise of unlocking quantum advantages and propelling scientific innovation in domains previously inaccessible to classical computing.
