There's a bunch of partialĭerivatives in here and Planck's constants, but the important thing is that it's got the wave function in here. He wrote down Schrodinger's Equation, and his name now is basically synonymous with quantum mechanicsīecause this is arguably the most important equation The mathematical description of this wave function We want a mathematicalĭescription of the wave and we wanna interpret whatĭoes this wave even mean. Wave function even mean? So we've got two problems. So at different points in x, it may have a large value, Systems are gonna have different wave functions, and this is psi, it's the symbol for the wave function. You a mathematical description for what the shape of the wave is. They wanted a mathematical description for the shape of that wave, and that's called the wave function. Grappling with this issue, trying to conceptually understand how to describe the wave of the electron. But it's hard to imagine, how is this electron having a wavelength and what is the actual wave itself? So physicists were This string itself is moving up and down and it extends through space. A wave on a string, we know what that is. I mean a water wave, we know what that is. Was like wait a minute, if this particle has wavelike properties and it has a wavelength, what exactly is waving? What is this wave we'reĮven talking about? Conceptually it's a little strange. When DeBroglie showed that the wavelength is Planck's constant over the momentum, people were like cool, it's pretty sweet. Underlying all of that is hardware with world-leading device metrics fabricated with unique processes to allow for reliable yield.- So when people first showed that matter particles like electrons can have wavelengths and This achievement wasn’t a matter of building more qubits instead, we incorporated improvements to the compiler, refined the calibration of the two-qubit gates, and issued upgrades to the noise handling and readout based on tweaks to the microwave pulses. Today, we maintain more than two dozen stable systems on the IBM Cloud for our clients and the general public to experiment on, including our 5-qubit IBM Quantum Canary processors and our 27-qubit IBM Quantum Falcon processors-on one of which we recently ran a long enough quantum circuit to declare a Quantum Volume of 64. Continued refinements and advances at every level of the system from the qubits to the compiler allowed us to put the first quantum computer in the cloud in 2016. IBM has been exploring superconducting qubits since the mid-2000s, increasing coherence times and decreasing errors to enable multi-qubit devices in the early 2010s. Members of the IBM Quantum team at work investigating how to control increasingly large systems of qubits for long enough, and with few enough errors, to run the complex calculations required by future quantum applications. All the while, our hardware roadmap sits at the heart of a larger mission: to design a full-stack quantum computer deployed via the cloud that anyone around the world can program. This roadmap puts us on a course toward the future’s million-plus qubit processors thanks to industry-leading knowledge, multidisciplinary teams, and agile methodology improving every element of these systems. In order to house even more massive devices beyond Condor, we’re developing a dilution refrigerator larger than any currently available commercially. Our team is developing a suite of scalable, increasingly larger and better processors, with a 1,000-plus qubit device, called IBM Quantum Condor, targeted for the end of 2023. Today, we are releasing the roadmap that we think will take us from the noisy, small-scale devices of today to the million-plus qubit devices of the future.
