Lin Yun raised her right hand and reached over to the major’s epaulet on her left shoulder—not to take it off, but to rub it.
Ding Yi noticed that her finger dragged an afterimage behind it.
When Lin Yun’s hand touched the epaulet, it was as if time stopped. This was the final image she left in the world. Her body began to turn transparent, swiftly turning into a crystalline shadow, and then the quantum-state Lin Yun vanished.
Victory
It was bright outside when Ding Yi finished his tale. The war-ravaged city had welcomed another morning.
“You tell a good story. If the purpose was to comfort me, then you succeeded,” I said.
“Do you think I’d be able to invent all that you just heard?”
“How did she remain in a quantum state for so long without collapsing with all of you observing her?”
“There’s one thing I’ve been pondering ever since I first posited the existence of the macro-quantum state: a sentient quantum individual is different from an ordinary non-sentient quantum particle in one important way, and we overlooked an important parameter for the wave function describing the former. Specifically, we overlooked an observer.”
“An observer? Who?”
“The individual itself. Unlike ordinary non-sentient quantum particles, sentient quantum individuals can engage in self-observation.”
“Okay. But what does self-observation imply?”
“You’ve seen it. It can counteract other observers, and maintain the quantum state uncollapsed.”
“And how is that self-observation conducted?”
“No doubt by some highly complicated emotional process that we’re unable to even imagine.”
“So will she return again like that?” I asked, full of hope for the answer to this critical question.
“Probably not. Objects that experience resonance with macro-fusion energy will, for a period of time after the resonance is complete, have an existence-state probability higher than their destroyed state. That’s why we were able to see all of those probability clouds of chips as the fusion was going on. But the quantum state will decay as time moves onward, and eventually the destroyed state will be more probable than the existence state.”
“Oh—” I exclaimed, the sound coming from deep within my heart.
“But the existence-state probability, no matter how small, is still there.”
“Like hope,” I said, doing my best to throw off my fragile emotional state.
“Yes. Like hope,” Ding Yi said.
As if to answer him, we heard a commotion out on the street. I went to the window and looked down to see lots of people outside. More were streaming out of the buildings, gathering excitedly in threes and fives. What surprised me most were their expressions: everyone was beaming like the sun had risen early. This was the first time I had seen this sort of smile since the start of the war, and now it was on so many faces.
“Let’s go down,” Ding Yi said, picking up the half-finished bottle of Red Star from the table.
“What’s the booze for?”
“We might need it when we get down there. Of course, in the unlikely event I’m wrong, don’t laugh at me.”
We had just exited the building when someone from the crowd ran over to us. It was Gao Bo. I asked him what was up.
“The war is over!” he shouted.
“We surrendered?”
“We won! The enemy alliance dissolved, and they’ve declared unilateral ceasefires. One by one, they’ve begun to pull back. Victory!”
“You’re dreaming.” I turned from Gao Bo to Ding Yi, who didn’t seem surprised at all.
“You’re the one who’s dreaming. Everyone’s been focused on the progress of the talks the whole night. Where have you been? Zonked out?” Gao Bo said, then ran off joyfully to join an even bigger crowd.
“Did you anticipate this?” I asked Ding Yi.
“I don’t have that foresight. But Lin Yun’s father predicted it. After Lin Yun disappeared, he told us that macro-fusion would probably end the war.”
“Why?”
“It’s simple, really. When the truth about the chip burn-out catastrophe got out, the whole world was frightened.”
I smiled, but shook my head. “How? Not even our thermonuclear weapons frighten anyone that much.”
“There’s a difference between this and thermonuclear weapons—a possibility you may not have realized.”
I looked at him, baffled.
“Think about it. If we detonated all of our nuclear bombs on our own soil, what would happen?”
“Only an idiot would do that.”
“But supposing that we have lots of macro-nuclei that can fry chips, a hundred or more, and we keep conducting macro-fusion on our own territory. Is that still idiotic?”
At Ding Yi’s prompting, I soon understood his point. If a second, identical macro-fusion took place on the same spot, the fact that the first had fried all the chips in the vicinity would mean the energy of the second would not be drained. It would pass through the region cleared by the first and destroy chips in a larger region beyond that until it, too, was drained by the chips it encountered. Proceeding in that manner with multiple macro-fusions on the same spot, fusion energy could propagate throughout the world. The Earth would be transparent to it. Perhaps fewer than a hundred strings of that type would be enough to temporarily return the entire world to an agricultural age.
There was one other important point: indiscriminate use of conventional nuclear weapons would take humanity out with them, so under no circumstances would politicians with even a shred of reason make such a decision. And even if some crazed strategist gave an order, it was unlikely to be executed. But macro-fusion was different. It could achieve strategic objectives without killing a single person. Hence the decision to use it was a relatively easy one, compared to conventional nukes, and when a country was backed into a corner, it was very likely to do so.
Chip-frying macro-fusion would reformat the world’s enormous hard drive, and the more advanced the country was, the harder it would be hit. The road to recovery back to the Information Age would lead to an undetermined new world order.
Now that I understood this, I knew I wasn’t dreaming. The war really was over. As if a string on my body had been plucked out, my legs crumpled beneath me and I sat on the ground watching the sky dumbly until the sun rose. In the deceptive warmth of the first ray of sunlight on that day, I covered my face and wept.
Around me, the sounds of celebration rolled on in waves. Still crying, I stood up. Ding Yi had disappeared into the reveling crowd, but someone immediately hugged me, and then I went and hugged someone else. I lost count of the people I hugged on that grand morning. As the dizzy joy ebbed somewhat, I found myself hugging a woman. When we let go, we happened to look each other over for a moment, and I froze.
We knew each other. She was the pretty student who had said I had a strong sense of purpose on that late night in the university library so many years ago. It took me a while, but I remembered her name: Dai Lin.
The Quantum Rose
Two months later, Dai Lin and I got married.
After the war, people’s lives turned far more traditional. Single people got married, and childless families had children. The war had made people cherish things they used to take for granted.
During the slow economic recovery, times were hard, but they were warm. I never told Dai Lin of my experiences after graduation, and she never spoke of hers. Clearly all of us had a past in those lost times that it was hard to look back on. The war told us what was truly valuable: the present and the future.
