The Quantum Thief

Scattered Trojan asteroids, clustered around 2006RJ103, a two-hundred k nugget of rock, inhabited by slow-brained synthlife.

The Prison, a diamond doughnut thirty lightseconds behind them, the origin of Perhonen’s current vector, dense, dark and cold.

The Archon bladeships, coming in fast at a .5g, much more delta-v than the gentle tug of Perhonen’s lightsail. The torches of their antimatter engines are fiery pillars of backscattered mesons and gamma rays in the spimescape.

The Highway, twenty lightseconds away, their next way-point. A constant torrent of ships, one of the few rare ideal invariant surfaces in the N-body Newton’s nightmare of the Solar System, a gravitational artery that lets you travel fast and easy with the gentlest of pushes. A safe haven, too far away.

All right, breathes Mieli. Combat mode.

The hidden Sobornost tech beneath the Oortian sapphire coral wakes up. The spidership reconfigures itself. The scattered modules pull themselves together along their tethers and fuse together into a tight, hard cone. The q-dot winglets transform from a perfectly reflective material into a diamond-hard firewall.

Just in time, before the Archons’ nanomissiles hit.

The first volley is just a series of thistledown impacts that fail to penetrate. But the next batch will adapt and optimise, and so will the ones after that, over and over and over until either the software or the hardware of the firewall collapses. And after that—

We need to get to the Highway.

The engines in her mind prune the game-theoretic branches like diamond-bladed chainsaws. There are many paths through this, like meanings in an Oortian song, and she only needs to find one—

Another barrage, innumerable needles of light in the spimescape. And this time, something gets through. One of the storage modules blossoms into a misshapen sapphire growth. Calmly, she ejects it, watches it drift away, still mutating and shifting in slow motion like a malignant tumour, forming strange organs that fire molecule-sized spores at Perhonen’s firewall until she burns it with the anti-meteorite lasers.

‘That hurt,’ Perhonen says.

‘I’m afraid that this will hurt a lot more.’

She burns all the delta-v in their emergency antimatter in one burst, swinging the ship into the shallow gravity well of 2006RJ103. Perhonen’s flesh groans as the antiprotons from the magnetic storage ring turn into hot jets of plasma. She diverts some of the power to pumping up the binding energies of the programmable matter rods in the hull. The Archons follow without effort, approaching, firing again.

Perhonen screams around Mieli, but the autism keeps her mind on the task at hand. She thinks a q-dot torpedo around the strangelet in Perhonen’s tiny weapons bay and fires it at the asteroid.

There is a brief flash in the spimescape, gamma rays and exotic baryons. Then the rocky lump becomes a fountain of light, a lightning flash that does not end. The scape struggles to keep up, turns into white noise and goes down. Flying blind, Mieli spreads Perhonen’s wings again. The particle wind from the strange death of the asteroid grabs them and hurls them towards the Highway. The acceleration makes her heavy, suddenly, and the sapphire structure of the ship sings around her.

It takes a moment for the scape to come back up and to filter out the particle noise and the madness. Mieli holds her breath: but no black fang-like ships emerge from the slowly expanding incandescence behind them. Either they were consumed, or lost track of their target in the subatomic madness. She lifts the autism to let herself feel a moment of triumph.

‘We made it,’ she says.

‘Mieli? I don’t feel so good.’

There is a black stain spreading in the ship’s hull. And in the centre of it, is a tiny black shard, cold and dark. An Archon nanomissile.

‘Get it out.’ The fear and disgust taste like bile after the combat autism, raw and foul.

‘I can’t. I can’t touch it anymore. It tastes like the Prison.’

Mieli shouts a prayer in her head, at the part of her mind that the Sobornost goddess has touched. But the pellegrini does not answer.

Around me, the ship is dying.

I don’t know what Mieli did, but, judging by the miniature nova that lit in space minutes ago, she is putting up a good fight. But now there is a spiderweb of blackness spreading into the sapphire in the walls. That’s what the Archons do: they inject themselves into you and turn you into a Prison. There is a burning sawdust smell as the nanites work, faster and faster, overcoming whatever immune systems the ship is throwing at it. There is a noise, too, the roar of a forest fire.

It was too good to last, I suppose. Fair cop, guv. I try to remember the thrill of stealing Mieli’s jewel. Maybe I can take it with me. Or maybe it’s all another dying dream. I never left. This was just a prison within a prison, all along.
