#Quantum error correction ramp software#
The limitations they have are mostly software not researching physics. The nature of their rapid development is promising. They have eliminated entire categories of possible error. I believe that based upon the nature of their technology, that their error rates are very low. The more qubits you have the longer it takes to test and prove the error rate. They have not been able to fully test the error rates of their systems. In the rapidly moving area of quantum computing, this has emerged as the most promising project. All quantum computer projects have what they can announce and what is in development. They have another system that they already have in development. I think they could quite rapidly reach many hundreds or thousands of qubits. They are not taking the time to prove it. I believe they may have the most powerful computer in the world of any kind. They have done all this with only $22 million in funding from GV (Google Ventures), NEA (New Enterprise Associates) and Amazon AWS.
They will ramp up improvement faster and then release when their lead and financing is such that they can support a product without slowing development. Their strategy is to not release a commercial product now. They are making revolutionary performance advances every day. IonQ is ramping up their improvement at a very fast rate. You would need say one billion qubits to get to one million error corrected qubits. * Error correction means you need a thousand times more qubits to get a number of useful error corrected qubits. They believe the error rates will let them get to thousands of qubits before error correction is needed. * IonQ has a confident path to scaling to thousands of qubits. You get more benefit by pairing them with a lot of classical computers to process the data. The reason for data centers is because the quantum systems generate so much data. * IonQ will have quantum systems at specialized data centers and then at regular data centers. * Superconducting systems had proposed or were using access via a remote cloud computing submission of problems. This cooling limits the size of the systems Superconducting quantum systems need extreme cooling. * They can have modular scaling which is not possible or practical with the superconducting systems.
* They could make 100-200 qubit modules and link them with optical interconnects. * There are no idle errors, no readout errors and no qubit lifetime problem * There are no errors from the fabrication of the qubits as the qubits are ions and not Josephson junctions. It is a matter of software and tuning laser pulses. * IonQ can invent and make any kind of quantum gate. * IonQ are like atomic clocks, they do not have time limiting decoherence * IonQ manipulates ions with magnets and lasers and have software control on mostly FPGA chips Highlights From the Nextbigfuture Interview with Stewart Allen The Q2B conference website is at this link and was organized by QCware. This is more qubits than the best noisy superconducting quantum computers which is currently the Google 72 Qubit Bristlecone processor. IonQ just made a presentation on two new trapped ion quantum computers with 160 stored and 79 processing qubits.
