The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in understanding the importance of surface preparation and the effect of surface oxides, the complex effect of superconductor film structure on microwave losses is not yet fully understood. In this study, ... Read more ..read more

A new algorithm can further exploit the twin challenges of information loss and translation to mimic a quantum computer with far fewer resources than previously thought. It was previously though that quantum computers with 50-100 logical low error qubits would be able to surpass regular supercomputers. New algorithms are showing that regular computers could beat ...

QuEra Computing, the quantum computing trailblazer, today announced a bold strategic roadmap for a series of error-corrected quantum computers, starting in 2024 and culminating in a system with 100 logical error-corrected qubits. This announcement marks the ushering in of a new era in quantum computing and caps off a banner year for QuEra, which included ... Read more ..read more

1. AGI could be achieved or we will get even closer. There will OpenAI releasing GPT5 and updates of Google LLM like improved Gemini. Definition’s for AI AGI = artificial general intelligence = a machine that performs at the level of an average (median) human. ASI = artificial superintelligence = a machine that performs at ...

1. Vladan Vuletic (MIT professor and QuEra Co-founder) had a scientific and technical presentation at the 2023 Q2B conference today. The main part of the talk came on the last slide where Vladan laid out his projection for how QuEra and its research partners will be able to advance their breakthrough Quantum Error Correction work. ...

Quantum computers leverage some aspects of quantum physics to make computers. They can create huge amounts of quantum states but it is also difficult to make the actual algorithms to use the abundant states. A classical (regular) computer would need more atoms than are in the entire universe to match the number of quantum stats ... Read more ..read more

PsiQuantum has raised about $665 million and has a valuation of over $3 billion. PsiQuantum is developing a photonic quantum computer that will have millions of physical qubits and eventually millions of error corrected qubits. Their belief is that small scale quantum systems will not be useful and only large scale systems will be able ... Read more ..read more

Q-CTRL has raised a total of over $70 million. They provide quantum error suppression and quantum error mitigation to improve the performance of quantum computers (superconducting, trapped ion, neutral atom). They leave quantum error correction to the hardware makers. They are working with customers and a shipping parcel loading optimization problem is economically useful. The ... Read more ..read more
