IonQ Reveals The Most Powerful Quantum Computer Yet

IonQ has just announced the worlds most powerful quantum computer. At 79 qubits their “trapped ion quantum computer” breaks the previous record held by Googles 72 Qubit Bristlecone processor.

Scientists are constantly trying to entangle more qubits together so as to speed up performance. A measure of the computers accuracy is greater than 98% for both one-qubit and two-qubit operations performed inside of a 13 qubit arrangement, where each of those smaller operations are carried out in subsequent steps.

When IonQ took a crack at the Bernstein-Vazirani Algorithm which challenges them to determine an encoded number between 0 and 1023 , the computer held an average success rate of 73%.  Again – better and more accurate under more complex circumstances than any other result made public.

Unlike other quantum computers the IonQ prototype does not have any wires, nor does it require deep learning or artificial intelligence. Furthermore, it operates at room temperature – an extraordinary achievement that will allow the company to eliminate cost requirements for cryo-cooling, a huge obstacle to adopting quantum computers.

They have accomplished all of this with $22 million in funding from GV (Google Ventures), NEA (New Enterprise Associates) and Amazon AWS. The company believes they have answered all of the major physics questions and now all that’s left is to do is scale operations to encompass more qubits. Their first goal is to simulate complex systems in chemistry.


 

“Highlights From the Nextbigfuture Interview with Stewart Allen

* IonQ systems are at room temperature
* IonQ manipulates ions with magnets and lasers and have software control on mostly FPGA chips
* IonQ are like atomic clocks, they do not have time limiting decoherence
* IonQ can invent and make any kind of quantum gate. It is a matter of software and tuning laser pulses.
* There are no errors from the fabrication of the qubits as the qubits are ions and not Josephson junctions.
* There are no idle errors, no readout errors and no qubit lifetime problem
* They could make 100-200 qubit modules and link them with optical interconnects.
* They can have modular scaling which is not possible or practical with the superconducting systems. Superconducting quantum systems need extreme cooling. This cooling limits the size of the systems
* Superconducting systems had proposed or were using access via a remote cloud computing submission of problems.
* IonQ will have quantum systems at specialized data centers and then at regular data centers. The reason for data centers is because the quantum systems generate so much data. You get more benefit by pairing them with a lot of classical computers to process the data.
* IonQ has a path to optical networking.
* IonQ has a confident path to scaling to thousands of qubits. They believe the error rates will let them get to thousands of qubits before error correction is needed.
* Error correction means you need a thousand times more qubits to get a number of useful error corrected qubits. You would need say one billion qubits to get to one million error corrected qubits.”
