By shining a laser pulse sequence inspired by the Fibonacci numbers at atoms inside a quantum computer, physicists have created a remarkable, never-before-seen phase of matter. The phase has the benefits of two time dimensions despite there still being only one singular flow of time...
This mind-bending property offers a sought-after benefit: Information stored in the phase is far more protected against errors than with alternative setups currently used in quantum computers. As a result, the information can exist without getting garbled for much longer, an important milestone for making quantum computing viable, says study lead author Philipp Dumitrescu.
The approach's use of an "extra" time dimension "is a completely different way of thinking about phases of matter. I've been working on these theory ideas for over five years, and seeing them come actually to be realized in experiments is exciting."
The workhorses of the team's quantum computer are 10 atomic ions of an element called ytterbium. Each ion is individually held and controlled by electric fields produced by an ion trap, and can be manipulated or measured using laser pulses.
Each of those atomic ions serves as what scientists dub a quantum bit, or "qubit." Whereas traditional computers quantify information in bits (each representing a 0 or a 1), the qubits used by quantum computers leverage the strangeness of quantum mechanics to store even more information. Just as Schrödinger's cat is both dead and alive in its box, a qubit can be a 0, a 1 or a mashup—or "superposition"—of both. That extra information density and the way qubits interact with one another promise to allow quantum computers to tackle computational problems far beyond the reach of conventional computers.

Let’s put the nuclear defense system on them right away.
Not stable. not created in nature, and no implications beyond research. The universe does not look different because of this laboratory creation.
Nature does not obey “laws” created by homo sapiens.
We can attempt to discover what is happening “out there” but nature has its own rules—and many of them are totally unknown to us.

Arrogant scientists are usually a clue that homo sapiens is stuck in a false or partially false paradigm—often new discoveries cannot be made until the old scientists die.
They really are just making up bad science fiction as they go along. I wish was I was dumb enough to consume this story without a shred of critical thinking.
RRRRIIIIIIIGHT!
Whats a qubit?
“...despite there still being only one singular flow of time..”
That is a wholly unproven assertion.
“Not stable. not created in nature, and no implications beyond research. The universe does not look different because of this laboratory creation.”
Respected scientists in the 1600’s and 1700’s often said the same thing of electricity.
Correct.
How do you know it’s not created somewhere in nature?
“Respected scientists in the 1600’s and 1700’s often said the same thing of electricity.”
You left of the term “some” as fact is some scientits were exploring electricty in the 1600s, and some aspects of electricity were understood as far back as 600 B.C.
It took people a long time from understanding electricity to understanding how to conveneniently generate it “in bulk”.
Had Ben Franklin had enough time his experiments with lightening may have produced productive results before the age of Edison et al.
But life as we know it is not lived at the Quantum level, regardless of how that level is many layers below physical existence.
For nature to produce what the scientists produced in the laboratory, nature would have to somehow execute the similar means the humans did in the lab. There is no observations we know of that nature does that.
“Nature does not obey “laws” created by homo sapiens.”
But you think it - nature - obeys man-made laws created in a laboratory????
Any homo sapiens centric view of nature is a major error.
Nature does not care what we think about it.
- OR -
...this could be evidence of more than three dimensions and time.... a fourth dimension... which may be illustrating what actually exists but that we, three-dimensional creatures, cannot see.
