Hannu Rajaniemi: The Quantum Thief

The Archons are coming.

‘Whatever it was that you did,’ Perhonen says, ‘looks like they want you back.’

What did I do?

Mieli’s heart pounds as the pilot’s crèche embraces her. Something went wrong in the Prison. But it was just like the sims. Why are they after us? She summons the combat autism the pellegrini built into her. It enfolds her like a cool blanket, turns the world into vectors and gravity wells. Her mind enmeshes with Perhonen ’s, thinking fast thoughts.

Objects: Perhonen .

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.

Then I hear a mocking voice in my head.

Jean le Flambeur, giving up. The Prison broke you. You deserve to go back. No different from the broken warminds and mad Sobornost toys and the forgotten dead. You don’t even remember the exploits, the adventures. You are not him, just a memory that thinks it is-

Hell no. There is always a way out. You are never in a prison unless you think you are. A goddess told me that.

And suddenly, I know exactly what I need to do.

‘Ship.’

There is no answer. Damn it .

‘Ship! I need to talk to Mieli!’ Still nothing.

The cabin is getting hot. I need to move. Outside, Perhonen ’s wings are ablaze, like trapped aurora borealis, burning in space around us. The ship has so much acceleration that it actually has gravity now, at least half a g. But the directions are all wrong: below is somewhere towards the rear end of the central chamber. I scramble out of my cabin, grasp the axis handles and start hauling myself towards the pilot’s crèche.

There is a blast of heat and a searing light: an entire segment of the cylinder spins out to the void below. The only thing separating me from the vacuum is a soap-bubble wall of q-dots that flashes into being. But it is too late to cut the infection out. Hot sapphire fragments swirl in the air around me: one leaves a painful bloody brushstroke on my forearm, razor-sharp.

It is hot now, and the sawdust stench is everywhere. The blackness in the walls is spreading: the ship is burning, burning into something else. Heart beating in my chest like there was a Notre Dame hunchback making it ring, I climb upwards.

I can see into the pilot’s crèche through the sapphire: madly swirling utility fog like heat haze in the air, with Mieli suspended inside, eyes closed. I pound the door with my fist. ‘Let me in!’

I don’t know if her brain has been compromised yet. For all I know, she could already be in the Prison. But if not, I need her to get out of this. I try to get leverage from the pole and kick at the door with my heel. But it’s no use – unless either her or the ship tells the smart sapphire to open.
