Study enables predicting computational power of early quantum computers

Sussex study enables predicting computational power of early quantum computers. University of Sussex quantum physicists have developed an algorithm which helps early quantum computers to perform calculations most efficiently The team used their model to calculate the expected computational power of early quantum computers Their research highlights a fundamental advantage of the 'trapped ion' approach over other methods Quantum physicists at the University of Sussex have created an algorithm that speeds up the rate of calculations in the early quantum computers which are currently being developed. They have created a new way to route the ions - or charged atoms - around the quantum computer to boost the efficiency of the calculations. The Sussex team have shown how calculations in such a quantum computer can be done most efficiently, by using their new 'routing algorithm'. Their paper "Efficient Qubit Routing for a Globally Connected Trapped Ion Quantum Computer" is published in the journal Advanced Quantum Technologies . The team working on this project was led by Professor Winfried Hensinger and included Mark Webber, Dr Steven Herbert and Dr Sebastian Weidt. The scientists have created a new algorithm which regulates traffic within the quantum computer just like managing traffic in a busy city.
