Key features of Starling include:

• Execution of 100 million quantum operations using 200 logical qubits 2

  2

• Ability to solve problems that would require the memory of more than a quindecillion of today's most powerful supercomputers 2

  2

• Implementation of quantum LDPC (qLDPC) codes to reduce qubit overhead by 90% compared to previous codes 4
