Alice & Bob

What a day for the quantum industry. 🌟 Google Quantum AI has just proven, beyond any reasonable doubt, that Fault-Tolerant Quantum Computing is possible. For the first time ever, a logical qubit meets all criteria, demonstrating that Quantum Error Correction is effective. 🚀 There are three key standards for a logical qubit to serve as a viable component in a useful quantum computer: ✅ Below Threshold: Integrating more physical qubits within a logical qubit significantly reduces errors. The more, the merrier! ✅ Breakeven: The performance of the logical qubit surpasses that of the best physical qubit involved. ✅ Repeatable and in real time: error correction cycles are executed in sequence on the same chip using the same qubits while errors are tracked as they occur. All benchmarks have been impressively achieved, marking a global first. 🌍 This advancement highlights the rapid pace of quantum computing; just two years ago, Google's researchers had a system that was barely at the threshold and had not yet achieved breakeven. It also underscores the leadership of superconducting circuits in Quantum Error Correction. 🏆 To the folks at Google Quantum AI: Keep up with the fantastic work! Truly inspiring for us all! Just don’t rest on your laurels, cats can sprint fast! 😏 Read the paper (which is beautifully written, as always!): https://lnkd.in/eGBk-3XC #LogicalQubit #QuantumComputing #FaultTolerantQC #FTQC #GoogleQuantumAI

It's time to look at things from a new angle. 🔍 Quantum computing's promise is one of unmatched compute power. With a fault tolerant quantum computer one may run operations that would otherwise take millennia. But as we edge closer to this frontier, a crucial question arises: can we achieve so without a massive energy footprint? ⚡️ We’re teaming up with Quandela, EDF, and CNRS on a unprecedented project to find out. 🤝 Yes, quantum computers could crunch certain problems with exponentially fewer steps than classical computers, but this doesn't always mean they're low on energy demand. We need to be intentional about designing quantum tech that’s energy-efficient right from the start. In this ambitious project, OECQ (Optimisation Energetique des Circuits Quantiques), we will begin by estimating the energy consumption of our quantum computers on industry use cases. Then, we’ll roll up our sleeves to develop new, energy-efficient quantum hardware. Our goal? Showcase a reduction in the energy footprint of our quantum chips by the project’s end. Building the first fault-tolerant quantum computer is one of this century's greatest technological challenges. Doing so responsibly is essential. 🌍 For more info, tap here ➡️ https://lnkd.in/eyXjcqW6 #QuantumComputing #EnergyEfficiency #TechInnovation

Out of the many challenges scientists face on the way to creating a Fault-Tolerant Quantum Computer, one thing just got easier. 🥳 The resource estimation. 🤔 What is it? Simply put, the resource estimator is like a crystal ball 🔮 for quantum algorithms. It helps us predict how many physical qubits and how much time we'll need to run complex quantum programs, given a target architecture. 🚀 Enhanced flexibility Up until recently, performing resource estimations on cat qubits had to be done by hand. This is how we showed that cat qubits may run Shor's algorithm using 200x fewer qubits. But because not everyone can dedicate a couple of months of a brilliant scientist's time to compute what their savings might be, we thought it was time to automate things a bit. Microsoft's Azure Quantum Resource Estimator was already working for the most common architectures, based on well-studied but resource-hungry surface codes. We collaborated with their team to help develop the API that supports Alice & Bob’s cat qubits. This means that in the months long process of developing a quantum algorithm, the resource estimation part now only takes seconds instead of days. Talk about a time saver! ⏱️ ⚙️ How does it work? The Azure Quantum Resource Estimator crunches numbers based on inputs like Q# code, or logical qubit and gate counts, and outputs optimal working parameters and necessary resources. For a more detailed explanation, take a look at our drawing below (don’t worry, we haven’t switched to chemistry… yet). 📚 Want to know more?
