As for quantum computers, however? Well, while GitHub userLumortihas createdQuandoom, a recreation of the first level of the iconic shooter designed to run on the esoteric and highly experimental hardware, even they admit that a quantum computer does not yet exist that’s powerful enough to run it. It is “effectively simulatable” on a laptop though, thanks to theQASM simulator.
Quandoom requires 70,000 qubits and 80 million gates to run. Currently, Atom Computing holds the record forthe most powerful quantum computer, with 1,225 qubits. So, we’re only looking at roughly 70x the qubits in order to enjoy ourselves a bit of Doom on a quantum machine then. No worries!
It’s not even the full version of the game, either. Aside from being an adaptation of just the opening level, Quandoom also has some tasty bare wireframe graphics. Lumorti also says that there’s no music or sound, enemies can’t travel between rooms, and the imp fireball is now hitscan rather than a projectile, which sounds like the least of your worries if you’re trying to get an ancient game running on more or less theoretical hardware.
Again though, like all of these attempts to force Doom to run on hardware that really wasn’t designed for it, it’s the sheeraudacityof the project that makes it interesting. Shrinking Doom down and tweaking it to high heaven in order to force it to run ona conference attendee badgeis one thing. But creating a version that runs on a quantum processor? I get a headache just thinking about how one works, never mind adapting a beloved game to run on it.
I’ll just sample you a quote here from the GitHub description, just to give you an idea of what it takes to translate something like Doom into, for want of a better term, quantum computing form:
“For now I’m still tidying up the engine code, but basically I have about 8,000 lines of C++ functions allowing a number of reversible binary and arithmetic operations on quantum registers, for example “flipIfLessThanOrEqualTo” which flips all qubits in a register if the value of another register is less than some given value. Everything is done with integers. Using such functions I then wrote a small 3D engine as well as all the game logic.
The biggest gaming news, reviews and hardware deals
Yep, nope, that lost me as well. Damn my basic brain, I guess. Speaking of which, did you know aYouTuber is growing a rat brain and teaching it Doom? Chalk one up for rats, I guess. I struggle to get mine to run “grammar.exe” while listening to a podcast.
