Scaling up quantum computers from dozens of qubits to millions is one of the most complex challenges across our industry. We’ve just published a paper that can have a huge impact on how quickly and efficiently we scale towards industrial relevance, via something called “safe lattice surgery” on high-rate codes. Read the scientific paper by here: https://lnkd.in/eZUBTm7d To run something like Shor’s famous algorithm, scientists have estimated that one would need thousands of “logical” (error corrected) qubits, which are each made from multiple physical qubits. There are almost infinite ways to construct logical qubits out of physical qubits, but some approaches have huge implications for how quickly #quantum computers can scale up. For example, one approach might take 20 physical qubits to build one logical qubit, while another might take only 5 physical qubits per logical qubit. When your scheme takes fewer physical qubits per logical qubit, scientists call it a “high-rate code”, and it is these “codes” that we are interested in developing. Of course, there’s no free lunch - we typically need extra qubits to do computation, which add an additional overhead in terms of physical qubit number. Once you have logical qubits, to perform “universal” computation, you also need things called “magic state distillation” and “lattice surgery” (there are other options, but for this post we will focus on this). Until our latest paper, scientists had only figured out how to do lattice surgery on “low-rate” codes (which we want to move past), or on high-rate codes but very inefficiently (using many ancillary qubits). In our new paper, we’ve developed an algorithmic method for performing safe lattice surgery on high-rate codes, efficiently. Our leadership in quantum error correction (QEC) would be impossible without our world-record commercial hardware fidelity. Quantum hardware that doesn’t have fidelity at our level will not be able to benefit from QEC in any meaningful way – until your hardware has good enough fidelity, QEC operations will only add noise. Our world-class fidelity, combined with our flexible QCCD architecture offering all-to-all connectivity, mid-circuit measurement, and feed-forward means that our team has an ideal playground for exploring the #QEC landscape, as we have proven over and over again.

Any sufficiently advanced technology is indistinguishable from magic. Famous words of Arthur C. Clarke. We are living in an era now where not only are these technologies advancing faster than ever but their real life application and eventual adoption is progressing at light speed. Imagine, what the application of quantum tech can do in the world of supply chain, where probability and predictability are so crucial. Whereas regular computers process information in 1's and 0's, quantum computers use quantum bits, or “qubits,” which can act as both 1 and 0. This lets each qubit perform multiple calculations simultaneously. The higher the number of qubits, the stronger the computation power. Technically, a quantum computer could perform calculations that a conventional computer cannot. Hence, the outcomes it can provide could also be vastly different and potentially superior. Just think about the applications to supply chain, transportation optimization, dynamic decision making on routing freight, disruption modeling, so many potential applications come to mind... #Technology #Quantumcomputing #supplychain #decisionmaking #optimization #Computers #qubits #predictivemodels

Have you ever touched a quantum computer? Well... until I had the opportunity to see Dirac-3 at the QuantumTech Conference in DC https://lnkd.in/dsxcgvBk neither have I ! ... See details here: https://lnkd.in/dSfnqFY2 Milan Begliarbekov the Director of Quantum Foundry and main drive in the development of Dirac-3 innovative technology, gave an impressive presentation revealing the tech behind this amazing creation based on a fundamentally new quantum computing approach called Entropy Quantum Computing (EQC). It roots deeply in the intriguing principles of quantum mechanics. You see, one of the main problems that builders of quantum computers encounter is that in quantum information processing, loss and noise are usually detrimental and must be minimized. This is why quantum systems using atomic and alike qubits must be hosted in cryogenic vacuum chambers, and why photon loss is the roadblock to quantum communications and computing. In designing Dirac, rather than trying to create and manipulate pristine qubits isolated from the environment, Milan instead flipped the script around. Instead of trying to avoid loss and noise, he harnessd them to build quantum machines whose capacity and speed outmatch existing computing modalities. Driac-3 utilizes loss and decoherence, and turns entropy into super-power fuels of its computing engine. In sharp contrast to any existing quantum platforms, there is no need for cryogenic or isolated housing, and the implementation can use integrated photonics, leading to SWAP-C friendly devices, just like regular PC’s. Having a PC-like quantum computer at this point in time is beyond my wildest dreams!... But wait! this is not all! QCi (Quantum Computing Inc), which manufactures Dirac-3 have also developed a pocket quantum device that you can attach to your laptop as a powerful "quantum extension" that you can carry around to enable you to do anytime anywhere powerful AI computing. EmuCore https://lnkd.in/dShRMH35 is a photonic-inspired, FPGA based device which can be applied to solve a variety of problems related to serial data structures including time series prediction, image recognition, and text classification.

Quantum computers, unlike traditional ones, use #qubits that can represent more than just 0 or 1, making them incredibly powerful for solving complex problems. One such problem is the travelling salesman's problem, where a person needs to find the shortest route through multiple cities and return home. As the number of cities increases, traditional methods struggle with the sheer number of possible routes, but quantum computers offer a faster and more precise solution. By harnessing #mathematical methods and leveraging qubits, quantum computers can tackle combinatorial optimization problems like the travelling salesman's problem much more efficiently than classical computers. This breakthrough could revolutionize industries like logistics and resource optimization.

If you’ve only just started to wrap your head around the Schrödinger-esque concepts of qubits, then I have some bad news—there’s another quantum technology in town. Powered by “qumodes,” next-gen quantum computers could possibly rely on these retooled laser beams rather than qubits to crunch 1s and/or 0s. Sometimes referred to as a continuous-variable (CV) quantum information, qumodes are the information-carrying units of a harmonic oscillator—in this case, light. Unlike qubits, qumodes technically contain an infinite number of states (though processors usually run with a finite amount of energy). So understanding and building upon this qumode concept could make quantum computers even faster than they are today. In a new paper published on Monday in the journal Science, scientists from the University of Tokyo successfully harnessed photons to create quantum calculations. To achieve this, the team “carefully modified laser pulses by removing one photon at a time and creating interference between pairs of pulses,” according to a Nature article. This could allow for only a few qumodes to essentially achieve the same computing power as hundreds of qubits. #quantum #computing #technology #lasers #qumodes https://lnkd.in/dGaCp-5j

Scientists have built an error-free "logical qubit" from a single laser pulse that works at room temperature. This breakthrough is a significant step towards a light-based, room-temperature quantum computer in the future. Typically, qubits are made from superconducting metals and need to be cooled to near absolute zero to avoid collapsing. By creating an error-free qubit, scientists have brought us one step closer to developing a practical quantum computer that can solve problems that classical computers cannot. #QuantumComputing #TechnologyAdvancements
