Quantum computers are life-size representations of composite quantum systems. Whereas classical computers process information by sequentially flipping digital switches representing 0s and 1s, quantum computers use units called qubits that represent multiple values simultaneously. Because they don’t need to process information sequentially, qubits can perform calculations significantly faster than bits, which can only do so using discrete values. Unlike quantum computers made by Google and IBM, which use superconducting circuits to create qubits, IonQ uses a special chip to isolate individual ytterbium ions and hold them in place using electromagnetic fields. The qubits are programmed by firing lasers at them,… Read More

In theory, this allows qubits to make calculations much faster, and in parallel, that digital bits would do slowly and in sequence. It is imperative to state that, although quantum sensing is not established as yet in quantum computation, it delivers simpler manufacturing difficulties. Quantum computation necessitates a huge quantity of qubits on uninformed superpositions with adequate coherence times to achieve the convoluted computations that exploit a great number of accesses. By contrast, quantum sensors necessitate a minor integer of qubits on a precise entangled formal. As a consequence, it seems that the expansion of quantum sensors delivers a tantalizing… Read More

Further, the interface between quantum information science and quantum sensing is significant; for instance, quantum SAR can be designated precisely as noisy quantum modes. Furthermore, quantum computation performance, established from the perspective of quantum control, will be invaluable to exploit quantum sensing hardware. Indeed, quantum theories are required to increase the performance of a broad diversity of conventional information processing sensors. In this sense, it is commonly tolerated that quantum communication and computer device talent develops information infrastructure systems. Furthermore, the interface between quantum information science and quantum sensing is significant; for example, quantum sensors can be designated precisely as… Read More

Using these collaborations, the NASA Advanced Supercomputing facility’s resources, and expertise in quantum computing, Ames works to evaluate the potential of quantum computing for NASA missions. Some say that annealing quantum computers are “limited” to optimization applications. But when you think about it, what endeavor is more urgent across organizations than getting the best possible return on the investment of resources? When a developer accesses quantum-classical hybrid solvers through the cloud, they don’t have to address that quantum annealing system directly. Instead they can rely on a front line of classical computing that shunts the appropriate portions of the workload… Read More

By expanding the range of states we can access (or, more precisely, the range of dynamical operations we can generate) beyond what’s possible on a classical computer, it becomes possible to take shortcuts in our computation. Of course, the XXX didn’t appear to do all that much beyond what is possible with a classical NOT gate. In this section I introduce a gate that clearly involves quantum effects, the Hadamard gate.

Quantum computing will do to traditional computing what Einstein did to Newton. The complexity of future quantum computers could be tamed by dedicated classical supporting electronics. To enable scaling, reduce footprint, and minimize power consumption we’re exploring the behavior of classical CMOS electronics at temperatures down to the millikelvin regime. Imec’s deep expertise in 3D integration on foundry-compatible 300mm platforms can be leveraged for quantum computing. Quantum computers, with their huge computational power, are ideally suited to solving these problems. Indeed, some problems, like factoring, are “hard” on a classical computer, but are “easy” on a quantum computer. This creates… Read More

As with any advanced technology, quantum computing raises its own anxieties and questions. In thinking through these issues, we’re following a set of AI principles that we developed to help guide responsible innovation of advanced technology. For example, for many years the security community, with contributions from Google, has been working on post-quantum cryptography, and we’re optimistic we are ahead of the curve when it comes to future encryption concerns. We will continue to publish research and help the broader community develop quantum encryption algorithms using our open source framework Cirq. We’ve appreciated the National Science Foundation’s support for our… Read More

The research portfolio now includes applications in nuclear and particle physics, plasma science, chemistry, and materials. It also includes improving the fundamental building blocks of quantum computers, developing sophisticated control to make the most of any group of qubits, and computer science research that will ultimately make quantum computers easier to use. IBM’s quantum computers are programmed using Qiskit, our open-source, Python-based quantum SDK. Since the latter gate makes no difference to the output from the computation, it can safely be omitted. We’ll see examples in the next essay, about the quantum search algorithm, where at a couple of places it… Read More
