A group of physicists say they created a new phase of matter by shooting lasers at a quantum computer. The matter phase depends on a quirk of the sequence to stay in a quantum state.
As ordinary matter can be in a solid, liquid, gas, or superheated plasmic phase, quantum materials have phases as well. The phase refers to how the matter is arranged on an atomic level. Physicists discovered a quantum supersolid several years ago and last year a team confirmed the existence of quantum spin liquids in a simulation. The team believes they have found a new phase.
Quantum bits, or qubits, are like ordinary computer bits in that their values can be 0 or 1, but they can also be 0 or 1 at the same time, a state of ambiguity that allows the computers to consider many possible solutions to a problem much faster than an ordinary computer. Classical computers can't solve problems like quantum computers can.
In the recent case, the researchers used 10 ytterbium ion to control electric fields and manipulate lasers. Multiple qubits can be described in relation to one another. When any one of the multiple qubits has a certain value, the agreement is dissolved. The system falls apart at that time.
Maintaining the quantum state of qubits is one of the biggest challenges of quantum computing. The calculations of the supersensitive qubits can fall apart when there is a slight change in the temperature, vibrations, or magnetic field. Making computers' quantum states persist for as long as possible is a crucial step for the field.
The 10 ytterbium qubits were kept in a quantum state for 1.5 seconds by a laser pulse. The researchers found that the qubits on the edge of the system remained in a quantum state for about six minutes. This summer, their research was published.
The two frequencies of the laser pulse are not related. The pulse is a quasicrystal because it has order but no periodicity.
Each number is the sum of the two previous numbers, so 1, 1, 2, 3, 5, 8, 13, and so on. The golden ratio is connected to its history of over two thousand years. The series might have quantum implications.
The paper's lead author and a quantum physicist who conducted the work while at the Flatiron Institute said that if you engineer laser pulse in the correct way, your quantum system can have symmetries. Regardless of when the experiment takes place, it will yield the same result.
The system can behave as if there are two different directions of time with the use of quasi-periodic sequences.
The system's quantum state was not prolonged by shooting the qubits with lasers. The qubits were given a non-repeating, or quasi-periodic, pattern by the researchers.
Instead of being a three-dimensional quasicrystal, the physicists made a quasicrystal in time. The tessellated patterns in a two-dimensional Penrose tiling can be projected in a lowerDIMENSION.
There is a complicated evolution that cancels out all the errors that live on the edge. He is referring to the qubits farthest from the center of their configuration. The edge stays quantum-mechanically coherent a lot longer than you would think. The edge qubits were more robust as a result of the laser pulse.
Longer-lived quantum systems are needed for the future of quantum computing. Physicists have better start blasting if it takes shooting qubits with a very specific mathematical rhythm of laserpulses to keep a quantum computer in an entangled state.
