Quantum computer science remain something of a holy grail in the world of technology : It promises a Brobdingnagian leap in cipher great power , but only if someone can figure out how to square away the defect rates that prevent any scaling of the technical school .
Now , one of the more promising quantum inauguration in Europe is announcing a crowing round of financing to help it process toward a resolution .
Alice & Bob , a Paris - free-base startup that is a pioneer in the area of cat qubit quantum architecture , has raised € 100 million ( $ 104 million ) . It plans to practice this Series B to go on working toward building a “ flaw tolerant ” quantum computer ( take over error and working around them ) based on cat qubits . Alice & Bob believes its first “ useful ” quantum estimator will be available by 2030 .
“ From the get go , Alice & Bob had a very vindicated vision of how quantum electronic computer should be made [ and ] it was all about fault tolerance , ” said CEO and carbon monoxide gas - founder Théau Peronnin in an interview . “ What we ’ve seen in the whole industry over the last 12 to 18 month is really a complete shift to coordinate with our vision . ”
The appetency for more computer science magnate is at the in high spirits it has ever been — a belief underscored by major projects like the$500 billion Stargate AI data centerfield commitmentin the U.S. , and the huge cost increase that computing chip Divine like Nvidia have escort in recent times .
As Peronnin sees it , the traditional computation architecture race is untenable in the longer streamlet , and that will drive more investment in quantum computing as it promise more efficiency than traditional processors .
“ Computing is becoming the core resource for productivity , and quantum is a potential secret plan changer here , ” he said . “ The game is on . ”

The investment funds is co - head by Qatari - backed Future French Champions ( FFC ) , AVP ( AXA Venture Partners ) , and Bpifrance , which also co - led itsSeries A of $ 30 million in 2022 . While the startup is not discover its valuation , for some guidance , Riverlane ( a mate of Alice & Bob ’s ) was valued last year at around $ 400 million . We read from multiple sources that Alice & Bob is at a comparable valuation , more likely between $ 300 million and $ 400 million .
The deal represents one of the large rounds for a quantum calculation startup in Europe . But notably for the quantum manufacture , it ’s not happening in a vacuity .
Some of the more far-famed fundraises in the place includeRiverlane , which also builds engineering science to discipline quantum error , resurrect $ 75 million ; quantum chip makerSEEQC , which raised $ 30 million in the beginning this month ; andQuantum Machines , which is reportedly also in the appendage of raising $ 100 million . Perhaps the biggest of all , last twelvemonth , Quantinuumraised $ 300 million at a $ 5 billion rating . There is nowtalkof it lean at a $ 10 billion valuation .
Meanwhile , Google had a breakthrough in the fracture - remotion race in November 2024 withAlphaQubit , an AI system of rules that it said could mechanically name errors in quantum computations . And , Microsoft and Atom Computingpromised they would release a commercial-grade quantum computer sometime this year .
The startup ’s name and the cat-o'-nine-tails qubit are both fundamental to what it is build . “ Alice & Bob ” is a mention to the two fictional characters that are often used asarchetypesfor hypothetical thought experiments in area like cryptography and quantum physics .
The construction block of Alice & Bob ’s system also has a theoretical reference in it . Rather than pursuing room to reduce faults by throwing more qubits at the problem ( qubits are the distinctive building stoppage of a quantum computation system ) , Alice & Bob devised an architecture that it calls a “ cat qubit . ” This is a reference toSchrödinger ’s catand the idea of something being in “ two states ” at once . efficaciously , it take on some faults ( hence “ fault tolerant ” ) while fixing others .
As Peronnin describe it , “ cat qubit is a peculiar design of qubit that is meant to correct errors now at the hardware level — not all of them , half of them , to be exact — but that is really the result of the cat qubit . It ’s to have this first layer of build - in error rectification . And the intellect why we went for that is because we believed it would dramatically simplify the full car . ”
Alice & Bob ’s investors believe this could be the key to making quantum a commercial reality .
“ Reality is at the inwardness of our public debate about quantum in the investment industriousness , ” François Robinet , a partner at AVP , said in an consultation . He articulate that while he has been take in Alice & Bob for years , AVP had n’t require to put before “ because it was just R&D ” like so many others . But now , he said , with quantum poker chip architecture appear to be able of stand 48 qubits , “ we believe the R&D phase is over . ”
François Charbonnier , a cooperator at Bpifrance , second this . “ Getting free one of two major errors , ” as Alice & Bob is doing , is the game changer for scale , he tell . “ Of course , it ’s still a foresightful - term battle of Marathon , but we are convinced that Alice & Bob will be in the race . ”
