Government investment for chasm-crossing
■ Europe €1B over 5 years
■ Individual countries also have initiatives,
■ Germany QUTEGA initiative likely
€300M over 10yrs
■ UK made £270M investment in 2013
■ Australia Center of Excellence at UNSW
■ Funded at $25M over 5yrs, 2016-2021
China has announced a $10B, four million square
foot national quantum laboratory in Heifi devoted
to quantum information sciences
Foreign governments have led the way with direct funding
Government investment for chasm-crossing
Proposal requiring legislative action by Congress
■ $800M over 5ys for civilian work + more on defense
■ 3-6 QILabs to be built out, focused on hardware innovation
■ QCAP (QC Access Program) is envisioned to allow gov’t purchase of
commercial quantum compute resources → at least $100m over 5ys
2019 DOE budget allocates $105M to quantum information science
■ National Labs = primary recipients of this spend
■ Exascale Computing Initiative $1.8 billion, some small portion of which will
go to quantum
NSF’s “Quantum Leap” initiative allocates $30M to quantum computing research
initiatives, and another $30M to innovative HPC research
■ Possible compute distribution to researchers via NSF grants
DARPA and the Army Research Lab have known spending of around $30M in
quantum initiatives
The US has led basic research and is starting to catch up on industry support
