Quantum computing and networking company IonQ has delivered a data center-ready trapped-ion quantum computer to the uptownBasel innovation campus in Arlesheim, Switzerland.
The IonQ Forte Enterprise quantum computer is the first of its kind to operate outside the United States and Switzerland’s first quantum computer designed for commercial use.
According to IonQ, Forte Enterprise is now online, servicing compute jobs while performing at a record algorithmic qubit count of #AQ36. The number of algorithmic qubits (#AQ) is a tool for showing how useful a quantum computer is at solving real problems for users by summarizing its ability to run benchmark quantum algorithms often used for applications.
A review of syntheticapertureradar image formation algorithms and implementations: a computational perspective.
✍️ Helena Cruz et al.
Designing synthetic-aperture radar image formation systems can be challenging due to the numerous options of algorithms and devices that can be used. There are many SAR image formation algorithms, such as backprojection, matched-filter, polar format, Range–Doppler and chirp scaling algorithms. Each algorithm presents its own advantages and disadvantages considering efficiency and image quality; thus, we aim to introduce some of the most common SAR image formation algorithms and compare them based on these two aspects. Depending on the requisites of each individual system and implementation, there are many device options to choose from, for instance, FPGAs, GPUs, CPUs, many-core CPUs, and microcontrollers. We present a review of the state of the art of SAR imaging systems implementations.
Researchers have developed a technique called “atomic spray painting” using molecular beam epitaxy to strain-tune potassium niobate, enhancing its ferroelectric properties.
This method allows precise manipulation of material properties, with potential applications in green technologies, quantum computing, and space exploration.
Material Strain Tuning
Dr. Ariel Zeleznikow-Johnston hopes to pick up the movement where Jones left off, albeit with the significant twist that his version does not require freezing. A research fellow at Melbourne’s Monash University, Zeleznikow-Johnston wrote the new book, “The Future Loves You: How and Why We Should Abolish Death,” which makes the case that cryopreservation is possible and should be more widely available. Rejecting the popular notion that death endows life with meaning as “palliative philosophy,” Zeleznikow-Johnston’s book instead argues a human’s connectome — a high-resolution map of all their brain connections — could be theoretically recorded perfectly before they die.
Once that happens, that same internal brain activity could be recreated through high-powered computers, while a new brain is grown in a vat via stem cells or some combination of the two. As such, Zeleznikow-Johnston is proposing a spiritual descendant to the cryonics movement (which he dismisses as “unscientific” and “unsubstantiated”), one where the focus is not on preserving tissues but on the “data,” so to speak, of our distinct connectomes.
“We have very strong evidence that the static structure of the neurons is enough to hold onto someone’s memories and personality.”
A new technology that can generate electricity from vibrations or even small body movements means you could charge your laptop by typing or power your smartphone’s battery on your morning run.
Researchers at the University of Waterloo have developed a tiny, wearable generator in response to the urgent need for sustainable, clean energy. It is also scalable for larger machines. Their paper, “Breaking Dielectric Dilemma: Polymer Functionalized Perovskite Piezocomposite with Large Current Density Output,” is published in the November edition of Nature Communications.
“This is a real game changer,” said Dr. Asif Khan, the project’s lead researcher and a postdoctoral fellow in the Department of Electrical and Computer Engineering at Waterloo. “We have made the first device of its kind that can power electronics at low cost and with unprecedented efficiency.”
Researchers at MIT have developed a design framework for controlling ultrasound wave propagation in microscale acoustic metamaterials, focusing on the precise positioning of microscale spheres within a lattice.
This approach enables tunable wave velocities and responses, and is applicable in fields like ultrasound imaging and mechanical computing.
Acoustic Metamaterials
In the future we can envision FASQ* machines, Fault-Tolerant Application-Scale Quantum computers that can run a wide variety of useful applications, but that is still a rather distant goal. What term captures the path along the road from NISQ to FASQ? Various terms retaining the ISQ format of NISQ have been proposed[here, here, here], but I would prefer to leave ISQ behind as we move forward, so I’ll speak instead of a megaquop or gigaquop machine and so on meaning one capable of executing a million or a billion quantum operations, but with the understanding that mega means not precisely a million but somewhere in the vicinity of a million.
Naively, a megaquop machine would have an error rate per logical gate of order 10^{-6}, which we don’t expect to achieve anytime soon without using error correction and fault-tolerant operation. Or maybe the logical error rate could be somewhat larger, as we expect to be able to boost the simulable circuit volume using various error mitigation techniques in the megaquop era just as we do in the NISQ era. Importantly, the megaquop machine would be capable of achieving some tasks beyond the reach of classical, NISQ, or analog quantum devices, for example by executing circuits with of order 100 logical qubits and circuit depth of order 10,000.
