IonQ, one of many companies developing a quantum computer, has announced a new trapped ion quantum computer with 79 processing qubits. The company claims this quantum computer should beat Google’s 72-qubit quantum computer, not just in terms of number of qubits, but also in total processing performance.
With no less than FOUR rocket launches by four different companies, today promised to be an epic one for space fans. But by mid-morning, two of the most anticipated launches, by SpaceX and Blue Origin, were scrubbed by glitches, while weather forced another launch delay in South America.
SpaceX and Blue Origin kicked off the launch attempts today (Dec. 18). A SpaceX Falcon 9 rocket was set to launch GPS III SV01, the first of an advanced new navigation satellite system for the U.S. military. At first the mission, initially scheduled for 9:11 a.m. EST (1411 GMT), slipped a few minutes to 9:34 a.m. EST as SpaceX prepared for launch at its Cape Canaveral Air Force Station pad in Florida. But seven minutes before liftoff, the Falcon 9’s onboard computer triggered an abort, forcing SpaceX to stand down for the day.
“We did have an abort,” SpaceX Firmware Engineer Tom Praderio said during live commentary. “This abort was triggered by the onboard Falcon 9 flight computer. The unfortunate part is that it has pushed us past our launch window today.” SpaceX had a 26-minute window for the launch attempt. The company will try again Wednesday (Dec. 19), with liftoff set for 9:07 a.m. EST (1407 GMT).
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal Small, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Of course, all the algorithmic rigmarole is also causing real-world problems. Algorithms written by humans — tackling harder and harder problems, but producing code embedded with bugs and biases — are troubling enough. More worrisome, perhaps, are the algorithms that are not written by humans, algorithms written by the machine, as it learns.
Profiles in science.
Donald Knuth, master of algorithms, reflects on 50 years of his opus-in-progress, “The Art of Computer Programming.”
When your computer stores data, it has to pause while the information moves from one piece of hardware to another.
But that may soon stop being the case, as scientists from MIT and the Singapore University of Technology and Design uncovered a new manufacturing trick that should let them build computers that don’t have those annoying delays.
The key is to sit back and let a virus — the biological kind — handle the assembly work.

IonQ was founded on a gamble that ‘trapped ion quantum’ computing could outperform the silicon-based quantum computers that Google and others are building. As of right now, it does. IonQ has constructed a quantum computer that can perform calculations on a 79-qubit array, beating the previous king Google’s efforts by 7 qubits.
Their error rates are also the best in the business, with their single-qubit error rate at 99.97% while the nearest competitors are around the 99.5 mark, and a two-qubit error rate of 99.3% when most competitors are beneath 95%. But how does it compare to regular computers?
According to IonQ, in the kinds of workloads that quantum computers are being built for, it’s already overtaking them. The Bernstein-Vazirani Algorithm, a benchmark IonQ is hoping will take off, tests a computer’s ability to determine a single encoded number (called an oracle) when the computer can only ask a single yes/no question.

A startup based in Maryland has released and tested an impressive new quantum computer that demonstrates the power of an occasionally overlooked quantum computing architecture.
Companies like IBM, Google, and Rigetti are developing new kinds of computer processors that rely on the mathematics of subatomic particles to potentially perform calculations difficult for classical computers to do. These devices use superconductors as the basis for their qubits. A company called IonQ, however, has now announced a state-of-the-art system that relies on the quantum nature of atoms themselves, and it’s one of the best-performing quantum computers yet.
Whether we will ever find a way to overcome the physiological trade offs that hold back immortality, or whether we will really be able to replicate human consciousness in a computer are questions too difficult for us yet to answer. But are those leading the charge against death at least inspiring us to lead healthy lives, or are they simply rallying against an inevitable fate?
