back to article The Osprey has landed: IBM's 433-qubit quantum processor

IBM has officially unveiled its Osprey quantum processor featuring 433 qubits, more than three times the qubits seen in its Eagle processor introduced just a year ago. The news comes soon after Fujitsu said it has designed hybrid quantum/HPC computing technology that automatically finds the "optimal" solution for complex …

    qubits, flamingos and buzzwords

    So how many instructions per second can it calculate?

    How quick to create analyse several petabytes of data and provide an outcome - or analyse weather/climate patterns?

    This all feels too buzz-wordy to be of any real world value to an end user.

      Real world value? Who the hell needs that?

      So far the record for a quantum computer using a modified version of Shor's Algorithm to factorise a number is working out that 3 times 7 makes 21.

      The big problem is maintaining coherence, with each increases in qubits you need even more "parity" qubits to provide error correction. But it's early days, that might be a solvable problem.

      Can we take 256 of those 433 qubits to represent they key of AES256, provide the cipher text and corresponding plain text, collapse the wave front and get the key?

      If not it seems all that hype about quantum computers instantly breaking traditional cryptography algorithms might be a bit over-done.

    A Potential Winner

    "Meanwhile, Fujitsu said that it was working towards offering customers a computing workload broker that will use AI to automatically select the most "optimal" resources for an application from a mix of HPC and quantum computing technologies."

    AI [✓], Quantum [✓], If they can somehow get blockchain into the mix, they would seem to have a surefire winner there.

    However, instead of using an actual quantum computer, this prototype uses Fujitsu's quantum simulator technology, announced in March

    Ah, see this is where the Nuclear Fusion guys are going wrong - hey these 8 coal-fired power stations are an example of new our "Fusion Simulator" - well that's great then - of course it works...

      Quantum Zeno effect

      Measure a particle and it is in one position. Stop measuring it, come back and measure again, and it is in another position. It moves only when it's not observed. Of course that is impossible, the particle is constantly interacting with everything around it, it is never un-observed.

      Well, unless you are not measuring the particle, but rather a net-effect between the particle and the observer. Then each time you measure it, you have a fresh observer, so a different net-effect in a different position.

      But you can hide that flaw in a model, the simulator simulates the model, not the real world. So it works in the simulator!

      Take an entanglement experiment. A crystal emits two photons, those photons head off in opposing directions to be detected by detector Bob and detector Alice respectively. Their measured properties at Alice and Bob do not correlate. Yet if you filter for one or more properties (successful entanglement), then the remaining properties all now correlate. A statistical test, the Bells test is proof there is no nefarious hidden variables between the measurement at Alice and the measurement at Bob, so the act of measuring the photon at Alice must be setting the properties of the photon at Bob. A spooky distance effect, impossible, yet it must be true because there is no other explanation.

      Well except....

      Alice and Bob and the emitter are all clamped to the same test rig. The motions of alice and bob are linked to that of the emitter. There is definitely a variable correlating them, they all move the same way. This experiment only produces a subset of experimental results filtered for the same motion. It is not even hidden and it is not flagged by the Bells test because the Bells test only operates on the post-filtered experimental result.

      So the properties like wavelength, polarization etc. are net effects between observer Alice and Bob and the photons. The photons have defined opposing properties, and the only thing you are correlating are Alice and Bob's oscillating state, such that the net effect then correlates. Since there are more Combinational properties than independent properties, there are more net effects than actual independent effects. So you only need to filter for a few of those combinations to cause all to net effect properties to correlate.

      Slap a VR headset on every Quantum Physicist, they can live in an unreal world, I don't think therapy is enough.

      and with the average intelligence of the green loony it should confuse them sufficiently that we'll still have lecy - win - win

    Coincidental perhaps ...

    "the 1,121-qubit Condor and 1,386-qubit Flamingo in 2023 and 2024 respectively — between the Osprey and its planned 4,000-qubit+ Kookaburra processor"

    All these birds are known for looking nice but producing lots of very smelly crap. I hope that fact does not relate directly to the design expectations of the machines ...
